A Generalized Formulation for Adaptive Pulse Compression of Multistatic Radar

Abstract

For the return signal at a radar receiver comprised of radar returns from K illuminating radars operating in the same spectrum in near proximity, the multistatic adaptive pulse compression (MAPC) algorithm has been shown to effectively separate and subsequently pulse compress the multiple signals such that range sidelobes and cross-correlation sidelobes are minimized in the mean square-error (MSE) sense. This previous formulation implicitly assumed that the K radars possess very good control of sidelobe emissions. However, sidelobe control on transmit results in mainbeam spreading and loss, which is often unacceptable. In this paper, a generalized framework is developed which accounts for all of the inherent signals that are incident at a given radar receiver. In general, these signals collectively originate from the respective transmit mainbeams and sidelobes of the K illuminating radars and are then reflected into the receive mainbeam and sidelobes of the given radar receiver
