摘　　要：针对相控阵机载PD雷达波束宽度随扫描角变化的特点,提出了中高重复频率的波形设计算法。算法从准则选择、重复频率的边界及相关约束条件三个方面深入地研究了波形设计问题,并对这三个方面所涉及的具体参数进行了细致的分析,阐明了各种参数间的相互制约关系,给出了波形设计的具体步骤。最后通过应用实例说明了该算法的有效性。Based on the characteristic of the beam-width changing with beam scanning angle in the airborne phased-array PD radar, a wave form design method is proposed. The method focuses on determination of N/M rule, pulse repetition frequency（PRF） boundary and restriction condition. Then all the parameters of three sections are analyzed in detail, the relations of parameters are illuminated, and the process of method is given. Finally, an example is given to demonstrate the effectiveness of the proposed method. This paper is very useful to waveform design for phased-array PD radar.
