Abstract:

An advanced transceiver design concept is described which outlines the process required for developing a spread spectrum adaptive processing transceiver capable of meeting the ECM threat. The design relies on the optimal integration of pseudo-noise band spreading techniques and adaptive cancellation scheme to achieve greater than 60 dB of anti-jam performance. Basic to the concept is the development of signal estimates and tracking algorithms to correctly control the PN code and the phase and amplitude of the received signals by an adaptive array. The theoretical basis for interconnecting spatial and temporal processors in a single, optimal space - time processor is presented. Appropriate simplifications in the theoretical optimum transceiver processing system are made in order to derive a realistic transceiver baseline architecture. For the baseline system, a paper design was synthesized. Implementation approaches considered were an all-digital approach and an analog approach for the highly adaptive processing subassemblies consisting of an adaptive array, colored noise filter, adaptive matched filter, and signal estimator.
