| 摘 要： | 分析了脉冲多普勒雷达导引头“遮挡”效应产生的原因，介绍了锵决“遮挡”的两种方法：记忆跟踪法和变PRF方法，提出了采用四种重频脉冲交替变换解决遮挡的方法，同时该方法能有效的解决导引头测距模糊问题。最后利用MATLAB软件对四重频脉冲进行了时域仿真，并对该方案进行了硬件实现。 |

| Abstract: | The reason of eclipse on pulse-Doppler radar seeker has been analyzed firstly. And the two methods on solution of eclipse have been introduced, which are tracking in memory and changing PRF. Secondly,the method of alternation on four pulse repetition frequencies has been put forward in this paper,and this method can reliably solve the problem of range ambiguity. The simulation result in time domain of this method has been given using MATLAB, and the circuit diagram has been designed finally. |
