Adaptive Pulse Compression of MIMO Radar Based on SIC

Abstract

Multiple-Input-Multiple-Output (MIMO) radar is recently the focus of radar research, which transmits different waveforms to illuminate the target from different antennas simultaneously. However the cross correlation of the waveforms may lead to interference between receiving signals. In this paper, we consider the use of adaptive pulse compression based on successive interference cancellation (SIC) to mitigate the mutual interference in MIMO radar receiver. The proposed method cancels interference successively on the pulse compression stage of each observation channel by subtracting the estimation of prior channel. The simulation results demonstrate the effectiveness of the proposed method.
