随着电子战仿真技术应用的不断深入，用户对电子战仿真环境的要求也越来越高。机载脉冲多普勒预警雷达海地杂波功率计算是电子战仿真研究的一个热点和难点问题。文章分析了机载脉冲多普勒预警雷达的杂波特性，给出了机载脉冲多普勒预警雷达主瓣杂波、旁瓣杂波以及高度杂波功率的数学模型。并进一步探讨了不同条件下机载脉冲多普勒预警雷达总杂波功率的计算方法。

The expanding application of EW simulation technology proposes higher requirements for the EW simulation environment. The calculation of sea/land clutter power to airborne PD early warning radar is a hot and difficult problem of EW simulation. The characteristics of sea/land clutter for airborne PD early warning radar are analyzed in this paper. Then this paper establishes the mathematical model of main-beam clutter, side-lobe clutter and altitude clutter power for airborne PD early warning radar, from which calculation method of overall cutter power to airborne PD early warning radar is discussed.
