摘　　要：针对多输入多输出(MIMO)雷达正交波形经脉冲压缩后距离旁瓣高的问题,提出一种基于过采样广义Prouhet-Thue-Morse(GPTM)序列和完备互补码(CCC)的MIMO雷达波形.在过采样GPTM序列的控制下,不仅可以使得基于CCC的MIMO雷达波形在模糊函数的零多普勒轴附近有效降低距离旁瓣,还可以在特定的多普勒频率附近消除距离旁瓣.最后,利用仿真,验证所设计波形的性能,并与已有同类波形的性能进行对比.In order to solve the problem of high range sidelobes after pulse compression in orthogonal waveform design of MIMO radar, a MIMO radar waveform based on oversampled generalized Prouhet-Thue Morse(GPTM) sequence and complete complementary code(CCC) was proposed. Under the control of oversampled GPTM sequence, the MIMO radar waveform based on CCC could effectively reduce the range sidelobe near the zero Doppler axis of the ambiguity function. It could also reduce the range sidelobe near arbitrary Doppler frequencies. Finally, the performance of the designed waveform was verified by simulation and compared with that of other similar waveforms.
