The Arbalet family of radios represents the latest generation of tactical communications equipment designed and built in the former Soviet Union. Intended for use by ground forces, the Arbalet family includes radios operating in the HF, VHF and UHF bands, both vehicle mount and manpack. They offer additional capabilities over the previous generation of radios. In addition to operating under microcomputer control, the Arbalet radios also provide an integral digital data mode, improved antenna tuning, digital preselector tuning and network protocol support. Also, channel scanning capabilities provide some immunity to jamming and interfering signals. Technical information about the radios is a result of physical exploitation performed at the Georgia Tech Research Institute (GTRI). The radios' operating modes and performance specifications are reviewed in detail, considering such issues as design approach and effectiveness, construction techniques, maintainability, and Western technology transfer. Finally an assessment is made of future capabilities and features of the next generation of radio systems produced by the former Soviet Union.<<ETX>>","PeriodicalId":206310,"journal":{"name":"Proceedings of TCC'94 - Tactical Communications Conference","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114001497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The FEBA is highly dynamic due to mobility of friendly and opposing forces, the uncertainty of battle action, severe and rapidly changing electromagnetic environment (EME) and rapidly varying communications load. These characteristics create challenges for communications systems that are to provide resilient, reliable, and survivable communications in this difficult environment. Packet radio is being proposed as a technology that can meet the communications challenges of the forward echelon battle area. Use of packet radio in forward area communications demands that the packet protocols automatically adapt to arbitrary and unforeseen multihop network topologies and unpredictable traffic conditions. An automatically adaptive forwarding protocol for multihop packet radio systems is presented. This forwarding protocol is compared to classic incremental-source forwarding. Performance figures developed using a detailed simulation are presented.<<ETX>>","PeriodicalId":206310,"journal":{"name":"Proceedings of TCC'94 - Tactical Communications Conference","volume":"374 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126173962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although there have been a number of research efforts regarding the design of MALPI networks, detectability analyses are typically carried out for a single network transmitter, rather than for the network at large. In this paper, we present a slightly different approach to analyzing the detectability of a MALPI network. It is assumed that the interceptor knows the basic parameters of the waveforms used (i.e., total bandwidth, number of channels, frequency hop rate, etc.). However, in the network detection scenario, we assume that the detection of any transmission(s) within the network by an unauthorised listener effectively compromises the network. What distinguishes this approach from conventional link intercept analysis is that the detection decision is based on reception of signal energy from multiple sources. Frequency hop code division multiple access (FH-CDMA) is considered.<<ETX>>","PeriodicalId":206310,"journal":{"name":"Proceedings of TCC'94 - Tactical Communications Conference","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126318707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All network nodes can easily obtain channel traffic loading and destination information by examining only the narrowband headers. Wideband synchronization is facilitated by using the end of the header transmission as a time index for wideband signal acquisition. Long signature sequences minimize the probability that two or more wideband packets will be transmitted with their sequences aligned, while avoiding the requirement that each receiver search for several different sequences as in a transmitter-oriented protocol. A common signature sequence facilitates packet broadcasting. Finally, flow control can be implemented by monitoring the CSMA narrowband channel and insuring that the network offered rate remains below the saturation point.<<ETX>>","PeriodicalId":206310,"journal":{"name":"Proceedings of TCC'94 - Tactical Communications Conference","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122515236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Visual information is critically important for tactical planning, target identification, threat analysis, situational awareness and force leverage. Battlefield communications take place under conditions which are far from ideal regarding communications, while digitised visual information is typically associated with large data structures. This combination of large data files and low bandwidths present a difficult problem. This paper describes an image compression technique based on fractal geometry which has been used to transmit live video over SINCGARS and low bandwidth phone lines. Frame rates as high as 30 frames per second for 8 bit gray images at 80/spl times/128 image sizes have been reached in surveillance type applications over 9600 bit per second modems.<<ETX>>","PeriodicalId":206310,"journal":{"name":"Proceedings of TCC'94 - Tactical Communications Conference","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124030445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The window is one symbol wide. After initial training, white Gaussian noise is added to the samples and the ANN's ability to generalize is tested. We then conduct additional training, using the noisy data, to test the ANN's ability to adaptively recover.

Many units will be operating beyond the line-of-sight coverage provided by multichannel radios or out of range of combat net radio. Satellites will provide communications to high priority users, but what about units unable to get satellite time? These units are connected to mobile subscriber equipment (MSE) nodes for voice and data service. This requires connecting MSE nodes with beyond-line-of-sight communications to other MSE nodes or to strategic communications. A high frequency-automatic link establishment (HF-ALE) interface is a solution to this problem for both voice and data communications. This interface also meets other requirements; MSE-to-aircraft interface for air ground communications; a small unit training interface when line-of-sight multichannel radios are not available; units on the move or when units are cut off from the larger operation; and interfacing with other service and government agencies. This paper will examine a voice and data HE-ALE radio interface at the MSE small extension node (SEN) switch. It will describe the components needed to provide short-haul HF communications: an HF-ALE radio, near vertical incident antenna (NVIS) and frequencies, and a packet radio interface for data. This will give small units (battalions and brigades) access to strategic telecommunications without the support of a large tactical network.<<ETX>>","PeriodicalId":206310,"journal":{"name":"Proceedings of TCC'94 - Tactical Communications Conference","volume":"402 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116083554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This frequency correction is sometimes referred to as frequency tracking because the controlled corrections are updated periodically to track changes in the contributing sources of these offsets. The technique presented generalizes one previously studied by Chandler (see IEEE Tactical Communications Conference (TCC-90) Proceedings, p.369-379, April 1990). It can be applied to time division multiple access (TDMA) networks where the measured receive frequencies of specific burst signals are used to adjust both the transmitter frequency and the tuned receiver frequency for signals that are later transmitted or received. The primary objectives of this study are to demonstrate that the technique of the previous study can be generalized by applying it successively to multiple signal types, to demonstrate that the procedure for optimizing the frequency correction factors of the previous study can be used for each of the multiple components or signal types of the generalized technique, and to illustrate by examples the performance improvement achieved by using the generalized technique with multiple signal types as opposed to the single-component technique based on one signal type.<<ETX>>","PeriodicalId":206310,"journal":{"name":"Proceedings of TCC'94 - Tactical Communications Conference","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121643628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Importantly, distribution will be encrypted from generation to end COMSEC device using a tiered system architecture comprised of a common suite of hardware and software. The components are the central facility (NSA), local management device (LMD) with local COMSEC management software (LCMS) and key processor (KP) peripheral, and a data transfer device (DTD).
