| 摘 要： | 用大时宽带宽信号是提高雷达距离、速度及其联合分辨性能的最常用方法之一。频率编码脉冲是一种大时宽带信号，具有良好的距离分辨性能和较窄的瞬时带宽。推导了频率编码脉冲信号及步进频率脉冲信号的模糊函数，分析了其距离、速度分辨性能及其相应关系，并就有效解决其距离-速度联合测量问题进行了讨论。

| Abstract: | One of measures generally taken to improve the performance of range resolution, Dopple resolution, Doppler resolution and rang-Doppler resolution is to apply wide time-band transmitted signal to radar. In this paper, the ambiguity functions of frequency-coded pulse signal and step-frequency pulse signal with nicer rang resolution and instantaneous narrow-band have been given as well as their eorresponding relation, both the rang resolution and Doppler resolution of rfequency-coded pulse have been studied. A method, which will bring about higher range-velocity resolution than that of frequency-coded pulse, has been studied. |
