分析归纳了机载火控雷达高、中、低三种脉冲重复频率波形的特点和适用性。基于实际作战需要，提出了一种波形设计的新思路，实现了各重复频率脉冲的自适应选择，以使雷达能够智能化的始终工作于最佳状态。并着重讨论了中重复频率方式下，改善对近距离高机动目标检测性能的一些策略，且在实际飞行实验中得到初步验证。

This paper begins with a study on the characteristics of the HPRF,MPRF and LPRF in the waveform design of airborne PD radar. Then a new adaptive waveform design scheme is presented. As a result an optimal waveform can be selected and the performance of fire control radar can be improved. Method for maneuvering target tracking in MPRF mode is analyzed emphatically. By use of this scheme, effective target detection is achieved in trial flight.
