摘要
针对脉冲多普勒体制雷达,从杂波特性入手,就雷达的动目标检测和杂波抑制技术进行了讨论,并举例说明有关指标的计算。经过工程实践验证,采用大动态范围的线性接收机和FFT数字信号处理技术相结合的方案,能获得更高的改善因子和杂波抑制能力。
The techniques for moving target detection and clutter suppression in pulse Doppler radar are discussed based on the analysis of radar clutter characteristics. Illustrations for calculation of the relevant performance indexes are also given. Engineering practices show that by combining the large dynamic range linear receiver with the FFT digital signal processing technique, a higher improvement factor and a better performance of clutter suppression can be obtained.
