摘　　要：研究了动目标显示(MTI)雷达的最小可检测速度(MDV)。首先给出了MTI雷达速度灵敏度的定义,然后介绍了通过改善因子计算MDV的方法,分析了影响MDV的有关因素,最后通过脉冲对消器仿真实验进行了验证。得出的结论是:MDV由杂波功率谱宽度和MTI滤波器阶数决定,与脉冲重复频率无关。In this paper, the minimum detectable velocity（MDV） of moving target indication（MTI） radar is researched. The definition of velocity sensitivity of MTI radar is proposed, then the method of calculating MDV by improvement factor is presented and the influence factors of MDV are analyzed. Finally, validation is made by simulations via pulse canceller. It is concluded that MDV is determined by the clutter power spectrum spread and the rank of MTI filter, not by the pulse repetition frequency.
