| 摘 要： | 低重频脉冲雷达因其脉冲重复频率低,测速时会产生严重的速度模糊,需要找到一种方法,让低重频脉冲雷达具备测速功能。文中提出一种低重频脉冲雷达的速度解算方法,利用FFT实现8通道窄带滤波器组,然后通过参差、速度差值、速度估计实现测速。仿真验证了该算法的有效性。

| Abstract: | Because the pulse repetition frequency of the low pulse repetition frequency(PRF) radars is very low and there is terrible ambiguity in radial velocity measurement,it is necessary to make low-pulse repetition frequency radar be capable of velocity measurement.This paper puts forward a method for velocity measurement of Low PRT Radar,using FFT to achieve 8-channel narrow-band filter banks.Velocity measurement is achieved by using velocity mixing,velocity difference and velocity estimate.The simulation results verify the availability and practical value of the method. |

| Keywords: | low PRF radars ambiguous in velocity FFT the elimination of velocity ambiguis |
