Implications of Adaptive Cancellation Array Processing for Design of a Space-Based Surveillance Radar

Abstract

We examine the system design issues associated with the use of adaptive jammer rejection in the context of possible specifications for a space- based surveillance radar. We show that the adaptive nulling requirements of the system cannot be considered in isolation. Adaptive processing has implications for the entire system, from design of the antenna array, through to the choice of ADCs and the requirements of subsequent coherent integration and detection processing. Three different classes of adaptive processing architecture are considered: the sidelobe canceller, the fully adaptive array, and the generalized sidelobe canceller. These are shown to achieve different trade-offs between inherent complexity, requirements upon the system specification, flexibility and performance.
