| 摘 要： | 分析了频率编码脉冲（frequency coded pulse, FCP）雷达工作原理;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——步进频率编码信号（frequency stepped signal, FSS）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2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、速度分辨率不变的情况下,2种方法都能有效的降低“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(FCP) signal radar has been analyzed,and the ambiguity function of the frequency coded pulse-signal has also been derived.A criterion named ambiguity similitude for optimizing FCP signal has been proposed and two coding rules for optimizing FCP signal have been presented.The optimized coding results have been given in the end.The high range-velocity resolution performance of optimized FCP signal has also been concerned in this paper. |
