Combined adaptive pulse compression and adaptive beamforming for multistatic shared-spectrum radar

Abstract

In this paper we present a method to reduce the interference between shared spectrum multistatic radars by performing joint adaptive pulse compression (APC) in conjunction with adaptive beamforming. A recently proposed algorithm based on a Minimum Mean Square Error (MMSE) formulation, Multistatic Adaptive Pulse Compression (MAPC) [1]-[3] has been shown to successfully suppress both range sidelobes and interference from multiple radars operating in the same spectrum. Here, we combine an adaptive beamforming component with the MAPC algorithm to enable further mutual interference suppression and hence better estimation performance such that the number of multistatic radars simultaneously operating in the same spectrum may be increased for the same mean-square estimation error.
