Orthogonal Pulse Compression Codes for MIMO Radar System

Inspired by recent advances in MIMO radar, we introduce orthogonal pulse compression codes to MIMO radar system in order to gain better target direction finding performance. We propose the concept and the design methodology for the optimized ternary pulse compression codes called the optimized punctured Zero Correlation Zone sequence-Pair Set (ZCZPS). According to codes property analysis, our proposed codes are able to provide the optimized autocorrelation and cross correlation properties during ZCZ. We also present a generalized MIMO radar system model using our proposed codes as pulse compression codes and simulate the target direction finding performance of the fluctuating and nonfluctuating system. The simulation results show that the more antennas used, the better target direction finding performance could be provided.
