摘要
针对雷达云雨动杂波中可见度检验面临的实际问题,基于“目标机晴空飞行+模拟慢动体杂波注入”的处理思路,文中对云雨慢动体杂波模型进行了讨论,该模型不仅考虑了杂波自身的强度、多普勒频移、谱线展宽三个因素,而且考虑了线性调频的因素。结合某X频段测高雷达的SCVm检验,给出了一种零中频I/Q双通道模拟云雨动杂波注入方案。实际检飞试验表明该方案便捷可行。
Aiming at the problems of weather clutter visibility measurement, based on the idea of ＂airplane flying in clear sky plus simulated motive clutter＂, the simulation model of motive weather clutter, which takes into consideration of the clutter magnitude, the Doppler shift, the spectrum extent and LFM, is discussed. One test project is given for a certain X-band heightfinding radar. Flight test indicates that the project is feasible.
