Research Institution
Coherent Logix, Incorporated (CLX) proposes to develop an adaptive anti-jam radio system (AAJRS) to provide accurate position, velocity, and time (PVT) to friendly military forces in the presence of strong RF interference. Interference may include obscured satellite view, jamming (intentional or not, adaptive or not), and multipath RF propagation conditions. These interference problems increase along shorelines and in urban or mountain settings. In Phase I, CLX will combine RF and advanced signal processing techniques to achieve (under various interference conditions) the PVT accuracy of GPS Precision Positioning Service (PPS) without interference. Specifically, CLX will investigate the use of adaptive antenna techniques, adaptive spectrum management, wideband modulation techniques, link security techniques, link reliability enhancement, and GPS receiver design, in a network context in which part of the network can lock onto the GPS grid and provide position information to the rest of the network. CLX will determine the RF and signal processing requirements and the overall system trade-offs for realistic RF environments. In Phase II, CLX will develop a model of the AAJRS and Concepts of Operation. CLX will perform concept simulations for several antenna configurations including GAS-1, and for a variety of key RF environments.
