Mismatched filter design in MIMO radar

Abstract

It was shown in the literature that MIMO radar can resolve much more targets in the angle than phased array radars. In order to resolve targets close to each other in range, waveforms, whose side-lobes of the autocorrelation function are low, are designed by using pulse compression techniques or mismatched filters are used at the receiver. In this paper, an integrated side lobe level filter which was originally developed for conventional radars is adapted to MIMO radar. In addition, a new mismatched filter design procedure is developed for the reduction of peak side lobe level.
