一种利用DDR3建立五维立体杂波图的实现方法

An Implementing Method of Establishing 5D Volume Clutter Map with DDR3

针对传统杂波图分辨率不高导致雷达对地物杂波和气象杂波抑制不充分的问题,提出了一种用DDR3建立五维立体杂波图的方法。该方法对杂波区进行精细划分,并对杂波数据位宽进行特殊处理,最后用DDR3-SDRAM存储精细杂波图。试验结果表明:该方法实现了杂波图精细设计,对于提高雷达检测能力和对杂波环境的适应性具有一定的工程价值。

Aiming at issue of radar suppressing ground object clutter and meteorological clutter inadequately caused by poor resolution of traditional clutter map,a method of establishing 5D volume clutter map by using DDR3 is proposed.Using this method can perform fine division for clutter zone,and perform special pressing for clutter data bit width,and save fine clutter map with DDR3-SDRAM.The test result shows that using this method can implement fine design for clutter map,which provides a certain applicable value in project for improving radar delectability and adaptability to clutter environment.
