| 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。这里使用二进制扩频码分多址信号作为不同发射天线的发射信号。由于编码相关产生的高旁瓣,传统距离压缩方法不能产生恰当的目标距离像。使用Capon波束形成方法来降低距离旁瓣,同时产生更高的角度分辨率,可用于对目标成像。

| Abstract: | Multiple-Input Multiple-output radar employs multiple antennas to make simultaneous transmission of orthogonal or non-coherent waveforms,and also multiple receiving antennas to receive and separate the reflected signals,thus forming a large virtual array.The Direct Sequence Code Division Multiple Access(DS-CDMA) sequences are used as the transmitting waveforms for the different antennas.Due to the high sidelobe of the code correlation,traditional code correlation range compression methods could not provide ... |
