中文摘要：

多输入输出雷达，利用多个天线发射和接收可分离信号。通过对发射波形的设计，可以明显地改善雷达的性能。Walsh编码与伪随机编码构造方法简单，但具有较高的互相关和自相关旁瓣。完全互补码具有良好的相关特性，其距离旁瓣为零，可用于对静止目标成像。

英文摘要：

The multiple-input multiple-output radar uses multiple antennas to simultaneously transmit and receive separable waveforms. Optimizing the transmit waveforms can improve the performance of the radar. Walsh codes and Pseudo random codes are easy to construct, but they have drawbacks of high cross correlation and auto-correlation sidelobes. Complete complementary codes have better correlation properties, and the range sidelobes are zero, so that they can be used in still target imaging.
