| 摘 要： | 分析了频率编码脉冲信号（FCP）雷达原理，推导了基于自相关函数的步进频率信号的模糊函数，针对常用的FcP信号一步进频率编码信号距离-多普勒旁瓣电平较高，存在“距离．速度”耦合，“距离．速度”联合分辨率低的缺点，提出了优化频率编码的模糊优化度准则，并基于该准则给出了两种编码优化规律不同的频率编码优化方法，仿真结果表明，在保持原有的距离、速度分辨率的情况下，两种方法都能有效地降低“距离．速度”二维耦合，提高“距离，速度”联合分辨率。

| Abstract: | In this paper the principle of frequency coded pulse signal radar was analyzed, the ambiguity function of the frequency-coded-pulse-signal is derived, with discussion of stepped frequency pulse signal. A criterion named ambiguity similitude for optimizing of FCP signal was proposed and two coding rules for optimizing of FCP signal was presented, and the coding results were expressed in the code of length N = 16. Also discussed is the high range-velocity resolution performance of optimized FCP signal. |
