摘要
研究雷达在多杂波环境下的自适应杂波抑制技术。针对多个或杂波功率谱具有多谱峰的气象杂波 ,导出了基于DSP实现的多级杂波抑制滤波器技术。仿真结果表明 ,此种方法对雷达回波中的多谱杂波具有良好的抑制效果 ,可较好地解决传统的单个杂波抑制滤波器对较复杂杂波谱抑制不够理想的问题。
The technique of adaptive clutter rejection in multi-clutter environment is discussed. A MTI filter with multi-stage based on DSP(Digital Signal Processor) is derived. Simulation results show that a satisfactory rejection for multi-clutter or multi-peak spectrum clutter is achieved. It solves the problems of a traditional mono-stage MTI filter in a multi-clutter case.
