Abstract

It has been shown that Multiple-Input Multiple-Output radar can dramatically improve the performance of a radar. In this paper, the Direct Sequence Code Division Multiple Access(DS-CDMA) sequence are used as transmitting waveforms for the different antennas. Due to the high sidelobe of the code correlation, conventional code correlation range compression methods cannot provide a proper range profile of the targets. In this paper, we find that range and cross range joint Capon beamforming provide a higher angle resolution but also suppress the range sidelobe.
