本文讨论杂波的频谱分布,目标特性。FFT分析指出杂波频谱的数学模型及杂波频谱截止频率与风速的关系。设计一实用的抑制杂波系统,利用其正,负多卜勒分别处理为正、负电平,长时间积分可检测强杂波中的慢速目标。对CW雷达回波振幅统计特性作了理论探讨。
This article discusses the clutter spectrum distribution, the target characteristics. FFT analysis points out the mathematical model of clutter spectrum and clutter spectrum cut-off frequency and wind speed relationship. Design a practical suppression clutter system, using its positive and negative Doppler were handled as positive, negative, long time integral can detect slow clutter in the slow target. The statistical characteristics of CW radar echo amplitude are discussed theoretically.
