摘要
通过对相位编码脉冲调制信号分析入手,基于常规脉冲雷达杂波模型,给出了相位编码脉冲压缩体制雷达下的杂波模型,并用蒙特卡罗方法分析了杂波回波信号的概率分布特性和功率谱特性,距离波门回波之间的相关性。最后给出了在雷达环境模拟器中,该类型杂波模拟的系统实现方法。
Firstly,the phase-coded pulse compression signa l is analyzed. Then the radar clutter model for phase-coded pulse compression rad ar is proposed based on the radar clutter model for the general pulse radar. Bot h the probability density characteristics and the spectral density characteristi csof the clutter signal are analyzed by Monte-Carlo method. The correlation cha racteristics of the clutter signal between the two range gates are also discuss ed. Finally,for the design of the radar environment simulator, the implementati on of the clutter simulation's system is proposed by mixed means of software and hardware.
