Moreover, modular architectures provide scalability, allowing low cost upgrades and adaptability to different platforms. To achieve maximum benefit from modularity and scalability, the challenge is to define the front-end concept in such a way that it supports multiple functions and is applicable in multiple environments and platforms. This paper describes concepts for such modular systems that may be used for RF functions in maritime, airborne and land based systems. The first part discusses general scalability properties of various RF functions, the second part discusses example system concepts in a ‘joint’ scenario (land/sea/air). The focus of this paper is on X-Ku band systems: considering essential RF functions like radar and communication, and the types of platforms in maritime, land-based and airborne operations, this frequency range provides the highest potential for application in all these domains and platforms. Conceptual designs for weapon location radar, SAR/GMTI, surveillance radar and tactical data link are presented.","PeriodicalId":125604,"journal":{"name":"2010 IEEE International Symposium on Phased Array Systems and Technology","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126293618","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 design of such tracking systems is complicated by the multiple subsystem functions involved in overall system performance. The separate isolated design of these functions results in suboptimal system performance. In this paper we consider the overall multiple radar system optimization by means of aperture waveform bandwidth allocation. In general, a greater aggregate bandwidth assigned to a target results in a more accurate target track. However, since multiple targets are simultaneously tracked, the data network transmission capacity limits the overall throughput resulting in a resource assignment problem. The assignment problem is specifically to assign available multi-radar bandwidth in a manner that maximizes the number of targets that achieve a terminal tracking error that is less than the maximum error allowed. We introduce a multistage control framework to demonstrate the performance of a proportional assignment procedure for countering a saturation attack. Conclusions for designing suitable distributed radar systems are given.","PeriodicalId":125604,"journal":{"name":"2010 IEEE International Symposium on Phased Array Systems and Technology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129907996","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 paper demonstrates that achieving the widest possible bandwidth from a phased array requires minimization or cancellation of the following: (1) signals traveling into the observation port from neighboring elements, (2) reflections from discontinuities in the geometry of the radiating element, (3) reflections from the edge of a finite connected array, and (4) reflections from the ground plane. An investigation of currents on various connected arrays demonstrates that shaping the radiating element to minimize reflections from the end of the array and interactions with neighboring sources is an important first step toward wideband phased array designs. Of particular interest are self-complementary radiators. The use of high impedance substrates is further demonstrated as a means to obtain ultra widebandwidth when self-complementary radiators are placed above a conducting ground plane. Finally, advanced finite element methods are briefly described for the efficient and accurate analysis of both infinite and finite ultra wideband arrays.","PeriodicalId":125604,"journal":{"name":"2010 IEEE International Symposium on Phased Array Systems and Technology","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128076305","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}

In particular, phased array packaging, especially at Ka and higher frequencies, is extremely challenging as half-wavelength spacing is prohibitively small. The cost of implementing high density phased array packaging is another impediment to wider use. This communication presents a new electronically beam-steering technology that is compatible with highly integrated antenna design and dramatically simplifies packaging. It is based on the coherent scattering of the evanescent field associated with waves propagating through a dielectric waveguide. The antenna scattering elements are controlled electronically and constitute a dynamically reconfigurable hologram. The switching time from one hologram pattern (one beam position) to another is on the order of tens of nanoseconds. Because of the hologram nature of this approach, the beam-forming capabilities of the electronically reconfigurable aperture (ERA) approach are comparable to those of phased arrays: 1D and 2D beam-forming and beam-steering, multiple simultaneous individually controlled beams, steerable nulls and variable beam width(s).","PeriodicalId":125604,"journal":{"name":"2010 IEEE International Symposium on Phased Array Systems and Technology","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129205553","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}
