摘　　要：给出了一种基于自适应多波束顺序比幅测角技术的三坐标雷达跟踪系统的设计方案。三坐标雷达测高系统中时常会因为障碍物遮挡波束或者RCS闪烁引起目标高度的突变。文中通过两种手段来改善测高时高度突变的问题,一种是在高度测量时采用自适应四波束顺序比幅测角技术,有效解决了三坐标雷达在测高时由障碍物遮挡和RCS闪烁引起的高度突变问题;第二种是在获得目标俯仰角后分别用α-β滤波和卡尔曼滤波处理数据过滤噪声,获取平滑的目标高度变化曲线。A design of three-dimension radar system based on self adapted beam sequence angle measurement is proposed. The measured target height can always be disturbed by obstacle and RCS blink in three-dimension radar system. The result of height measurement by two ways. The first approach is to apply self adapted four sequenced beam to get the pitching angle. The second approach is to apply α-β filter and kalman filter to pitching angle sequence.
