摘　　要：现有的MIMO类型雷达装置正交波形构建存在自关联旁瓣峰值以及互关联峰值结果大的状况,给出一种选取正交频分方式下的非线性调频方案OFD-NLFM。此方法采用OFD-NLFM方案能够最大限度地抑制自关联旁瓣和互关联旁瓣,得到自关联旁瓣和互关联旁瓣较好的正交波形集合。实验结果表明,此方法的自关联旁瓣和互关联旁瓣最高点结果均低于50 dB。Existing MIMO type radar apparatus constructed orthogonal waveforms exist autocorrelation peak sidelobe and interrelated health large peak results give a select orthogonal frequency division non-linear FM program OFD- NLFM mode. This method takes OFD-NLFM program to maximize the autocorrelation side-lobe peak （ASP）and the cross-correlation peak（CP） to give the autocorrelation sidelobes and interrelated set of orthogonal sidelobes better waveforms. Experimental results show that the highest point of two kinds of side lobe suppression associated with this method are all lower 50 decibels.
