受MIMO雷达最新进展的启发，本文将正交脉冲压缩编码引入MIMO雷达系统，以获得更好的目标测向性能。提出了优化删余零相关区序列对集（ZCZPS）的概念和设计方法。根据码的性质分析，我们所提出的码能够提供最佳的自相关和互相关特性在ZCZ。我们还提出了一个广义MIMO雷达系统模型，使用我们提出的编码作为脉冲压缩码，并仿真了起伏和非起伏系统的目标测向性能。仿真结果表明，天线数目越多，目标测向性能越好。
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.
