摘　　要：针对窄波束测控雷达天线自动跟踪捕获问题,首先,分析讨论目标引导和角度追踪方法及相关的时延修正、坐标转换、叠加扫描等理论,结合某型雷达提出天线自动捕获跟踪框架;然后,针对引导异常情况下快速追踪问题,提出基于接收电平、扫描范围和扫描速度的变步长天线追踪算法,通过修改伺服控制软件实现靶场雷达天线自动捕获跟踪;最后,通过理论分析和实验验证,该方法引导追踪捕获成功率高,可推广应用于同类型雷达。Aim to the two problems of radar automatic tracking and automatic acquisition,coordinate transformation,time delay correction,superposition scanning and other theories are analyzed. The automatic capture tracking framework by modifying the servo control software is proposed to solve the problem of fast tracking in the case of guiding abnormality. A variable step antenna tracking algorithm based on receiving level,scanning range and scanning speed is proposed to realize automatic capture and tracking of the target radar antenna. The theoretical analysis and experimental verification show that method can accurately and automatically track the target in the case of guidance abnormalities,and can be applied to radars of the same type.
