摘要
雷达杂波是影响雷达性能发挥的重要因素,同时雷达杂波量化也是雷达性能验证评估的重要依据。在工程应用中,基于种种考虑,对试飞环境下的杂波测量需利用本机雷达来测量杂波。然而由于其非杂波测量专用雷达,也带来了一定的局限性和难度,在杂波测量方案中要统筹考虑。文中将结合机载雷达工程杂波测量,介绍雷达杂波测量的方法以及需要注意的问题,重点分析了杂波测量系统校准方法,并给出部分典型杂波测量和分析结果。
Radar clutter is very important to radar performance,and the quantitative clutter evaluation is an important basis of evaluation of performance of a radar system.In engineer applications,for different reasons,it is required to measure the actual environment clutter by use of airborne radar per se.But the radar is not specialized for clutter measurement.So some problems are introduced,the measument plan must take them into account.In this paper,based on the clutter measurement of airborne radar,the method of clutter measurement is introduced,especially the calibration method of the measurement system.Furthermore,some typical measurement and analysis results are given.
