While the raison d'etre of SDR is somewhat different for military and commercial applications, they share similar challenges in implementing a true SDR. A true SDR faces numerous hardware and software challenges, many of them still to be addressed by research. In the literature concerning SDR software architecture and requirements, the technology requirements tend to be sidelined. This is mainly because, in the JTRS program, the focus is on voice and low data rate applications; also, the frequency band is limited to UHF. On the other hand, the implementation cost is less of a concern for now. However, by the emergence of advance warfare technology where it is required to transport more bits per warrior to accommodate video and telemetry data, and also by introducing initiatives similar to the JTRS to other communication systems, the technology requirements of SDR have to be revisited. The paper focuses on the hardware technology aspect of SDR. The main technical objective of SDR is a versatile reconfigurable platform, which provides interoperability. The main blocks of a true SDR are: intelligent antenna; programmable RF modules; high-performance digital-to-analog (DAC) and analog-to-digital converters (ADC); digital signal processing (DSP) techniques/technology; interconnection technology.","PeriodicalId":191931,"journal":{"name":"MILCOM 2002.

Mobility of the nodes in the network causes creation of new links or breaking of old links, changing network routes dynamically. These changes require a proactive routing protocol to regularly broadcast updates in the network to enable other nodes to maintain correct routing information. The performance of a proactive protocol depends on the particular strategy the protocol uses to broadcast these updates. The updating strategies used by the current proactive protocols to broadcast detected link changes in the network are found to be inefficient. We propose three new strategies for broadcasting proactive updates in the network. Analysis of these updating schemes using simulations shows that the proposed schemes lead to significant savings in the amount of routing control traffic generated in the network. At the same time, the performance of these schemes is satisfactory in terms of the data throughput, route success rate, etc. For example, for a moderately sized network, simulation results show that the proposed schemes can lead to more than 45% savings in terms of routing control traffic, while maintaining decent performance of the network.","PeriodicalId":191931,"journal":{"name":"MILCOM 2002.

The task of stabilizing the antenna mount on a moving platform as well as the capability to operate on more than one frequency band presents multiple challenges to the terminal designer. A team of companies have joined together to design and produce the next generation in marine stabilized multiband satellite communications terminal. Austin Info systems, Inc. (AIS) teamed with Maritime Telecommunications Network (MTN), Orbit CT&T Marine Division, and Ki Company to produce the 106M4S3 Satellite Terminal. The system consists of a 2.7-meter carbon fiber reflector system using the AIS patented multiband feed technology. The system provides continuous transmit and receive capability in C-band and Ku-band without the need for mechanical changeout of the feed assembly. The C-band is also provided with selectable circular or linear polarization. The system is supplied with dual band satellite electronics. The system uses X over Y pedestal technology to eliminate cable wrap. The system is capable of being provided in a single or dual terminal configuration. A complete monitor and control system is provided from below decks. Although originally designed for operation in C and Ku bands the system is capable of being expanded to provide coverage of other bands including X and Ka bands. This paper provides details of the design and operation of the system.","PeriodicalId":191931,"journal":{"name":"MILCOM 2002.
