Simultaneous Track and Search Multiple-Channel Multiple-User Receiver (MCMUR) for Joint Radar-Communications Systems

Abstract

A multiple-channel multiple-user receiver (MCMUR) exploits both spatial and temporal degrees of freedom to separate radar and communications signals coexisting jointly in the same frequency band, and to cancel interference waveforms. In this paper, we present the simultaneous track and search MCMUR, a novel mode of operation for the multi-antenna joint receiver. We discuss this novel operation of the receiver and present theoretical bounds on the detection and estimation performance of the simultaneous track and search MCMUR. We present a theoretically assessed receiver operating characteristic (ROC) analysis of the MCMUR herein to better understand the performance gains of the MCMUR at false alarm rates that are more informative of an actual radar systems' performance. We also measure the detection and estimation performance of the joint system through the detection and estimation information rates respectively.
