摘要
基于相控阵雷达工作原理,分析了天线扫描对波束宽度和天线增益的影响;以往只考虑相控阵雷达电扫法线跟踪测量精度,未考虑相控阵雷达偏轴电扫跟踪测量精度;通过雷达步进偏轴跟踪模拟目标方法,采集雷达角度补偿数据库,实现了偏轴扫描跟踪角度误差补偿;试验结果表明,该补偿方法能够提高相控阵雷达偏轴扫描跟踪坐标测量精度。
According to the principle of Phased Array Radar,this paper analyzed radar scanning influence on beam width and antenna gain.In previous measurement of radar scanning only the normal tracking precision was considered,but the off-axis tracking precision wasn't reckoned.In this paper method tracking simulated target by radar off-axis technique was advanced,database of radar angle compensation was collected and bias compensation of tracking angle by off-axis scanning was realized.The result of test indicates it can improve the coordinate tracking precision of radar off-axis scanning.
