摘　　要：多输入多输出雷达利用多个发射天线发射独立信号及多个天线接收回波信号,对回波信号进行分离。优化发射信号的设计,可以较大程度地提高MIMO雷达性能。二进制扩频信号虽然容易构造,但其互相关和自相关旁瓣较高。三进制互补集序列具有良好的相关特性,距离旁瓣为零,可用于目标成像。Multiple-Input Multiple-output radar uses multiple antennas to simultaneously transmit orthogonal or non-coherent waveforms and uses multiple receiving antennas to receive and separate the reflected signals.Optimization of the transmit signals can improve the performance of the MIMO radar.The binary spread spectrum code is easy to construct,but it has the drawbacks of high cross correlation and auto-correlation sidelobes.Ternary complementary codes,which have better correlation properties and zero range sidelobes,can be used for target imaging.
