摘要
提出了一种简捷的机载脉冲多普勒(PD)雷达地杂波相干视频信号的计算机仿真方法,阐述了具体的仿真过程,并给出了具体的计算公式。针对一个侧面阵雷达二维杂波的仿真结果,分析了不同的脉冲重复频率和不同的波束指向对时空二维杂波谱的影响。分析结果对机载PD雷达地杂波模拟和杂波抑制都有实际的指导意义。
A simple computer simulation method for ground clutter of airborne pulse doppler（ PD ） radar based on the analysis of coherent video is presented. The simulation process and formula are discussed in detail. Upen the simulated results of 2- D clutter for a side-looking radar,this paper discusses the influence of pulse repetition frequencies（ PRF ） and main beam direction on the spectrum of temporal - spatial 2-D clutter. The practicality of the analysis results for airborne PD radars clutter simulation and clutter suppression is apparent.
