摘　　要：在MTI雷达系统里,由于多次反射等原因造成的雷达二次回波在相邻脉冲重复周期内出现,这些回波是不需要的。为了抑制它并同时保证一次回波目标被检测,本文提出了一种基于LFM信号调制斜率脉间交变的MTI二脉冲对消方法,仿真结果验证了该方法的有效性。In MTI radar systems,the unwanted secondary echoes caused by various reasons such as multiple reflections usually appear in the adjacent pulse repetition periods.A two-pulse MTI cancellation method based on the pulse-to-pulse alternation of modulation slopes of LFM signals is presented to suppress the secondary echoes and at the same time ensure that the primary echoes are detected.The simulation results verify the effectiveness of the method.
