| 摘 要： | 首先分析步进频率雷达信号实现高分辨率的优缺点,在此基础上设计了一种改进的步进频率信号-参差脉冲重复间隔步进频率信号,然后分析了该信号的处理过程.与步进频率信号在高速目标下成像失真相比,参差脉冲重复间隔步进频率信号的多普勒性能有了很明显的改善.最后分析了参差脉冲重复间隔步进频率信号的低截获概率特性.

| Abstract: | Based on the advantage and shortage in stepped-frequency(SF) radar signal implementing high range resolution,a modified stepped-frequency radar signal-stagger PRI stepped frequency(SPRI-SF) signal is presented.Then the signal processing is analyzed.Compared with SF range profile distortion in the presence of high moving targets,SPRI-SF signal Doppler performance is obviously improved.Finally,the LPI of SPRI-SF radar signal is analyzed. |
