| 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 of Stepped-Frequency(SF)radar signal for implementing high range resolution,a modified Stepped-Frequency radar signal-Stagger PRI Stepped Frequency(SPRI-SF)is presented firstly. 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 Low Probability of Intercept(LPI)of SPRI-SF radar signal is analyzed. |
