| 摘 要： | 多输入多输出雷达使用多个发射天线发射独立的信号，使用多个天线接收回波信号，对回波信号进行分离，相当于形成一个大的虚拟阵列。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。复正交互补编码序列有着良好的相关特性，其距离旁瓣较低，可以降低旁瓣干扰影响，可用于对目标成像。

| Abstract: | Multiple-Input Multiple-output radar uses multiple antennas to simultaneously transmit orthogonal or non-coherent waveforms and it uses multiple receiving antennas to receive and separate the reflected signals,a large virtual array are then obtained.codes and Pseudo random codes are easy to be constructed,but they has drawbacks of high cross correlation and auto-correlation sidelobes.Orthogonal sequences using complex orthogonal compementary sets have better correlation properties and can generate lower range sidelobes,it can reduce the impact of the interference of sidelobe,which can be in applications of target imaging. |
