摘　　要：相控阵脉冲多普勒(PD)体制因在强杂波环境下能够有效探测运动目标,在机载雷达中得到了广泛的应用.相控阵机载PD雷达的天线波束宽度随扫描角的变化而变化,同时脉冲重复频率(PRF)的变化会影响雷达的杂波分布特性.鉴于波形参数优化设计是相控阵机载PD雷达研制过程中需要考虑的重要因素之一,首先深入分析了相控阵机载PD雷达各参数间的制约关系;然后对波形参数设计,给出了合理的波形参数选取准则;最后以X波段相控阵机载PD雷达波形参数设计为例,验证了所提系统化设计方法的有效性和可行性.Phased-array pulse Doppler (PD) system is applied widely in airborne radar because of its ability to detect moving targets effectively under strong clutter environments. The antenna beam-width varies along with the scanning angles, and the clutter distribution is affected by the pulse repetition frequency (PRF) configuration.In view of the fact that the optimization design of waveform parameters is one of the significantly considered factors during the airborne radar development process, this paper firstly analyzes in detail the restricted relationship between parameters of airborne phased-array PD radar, and then aiming at the waveform design,gives reasonable waveform parameters selection principles. Finally, the paper takes for example the parameter design of airborne X-band phased-array PD radar to verify the feasibility and effectiveness of the proposed systematic designing scheme.
