中文摘要：
由于多载频相位编码信号在频谱利用率、模糊函数以及包络峰均比三者之间达到了较好平衡,因而在近年来备受关注。针对这种雷达信号,研究基于子载频分离的脉冲多普勒处理技术,详细推导整个处理过程,分析速度对回波正交性及多普勒处理的影响,提出一种解决速度模糊的新方法。仿真分析表明,该方法能够较好地估计目标真实速度,对噪声具有一定的稳健性。
英文摘要：
The multi-frequency complementary phase-coded signal（MCPC） has caught much attention of researchers recently since it has gained good balance among spectrum efficiency,ambiguity function and peak-to-mean envelope power ratio（PMEPR）.Based on separation of sub carriers from multi-frequency structure,the pulse-Doppler processing method for such radar signal is introduced.After deducing the whole process and analyzing the orthogonality of echo affected by velocity,a new method of solving velocity ambiguity problem is presented.The simulation results show that this method can estimate the true velocity of target efficiently,and has good adaptability and stability against noise.
