针对强干扰环境下,雷达不能进行正确的目标检测、不能稳定跟踪目标的问题,介绍了一种基于边扫描边跟踪(Track-While-Scan,TWS)系统的三坐标雷达的干扰源跟踪实现方法。根据雷达扇区分区处理原则,完成干扰航迹的跟踪处理,主要包括航迹预测、航点相关及航迹滤波处理;同时,根据主通道和辅助通道接收到的回波功率,进行自动增益控制(AGC),提高干扰源测角精度。经试验验证,该方法能稳定地跟踪干扰源且跟踪精度较高。

When the radar is under strong jamming,correct detection cannot be performed,and the target cannot be stably tracked.An implementation method of jammer tracking is introduced,in which a 3 D radar based on trace-while-scan system is adopted. The tracking of jammer trace is performed according to the principle of radar sector partition processing,which mainly includes trace prediction,trace correlation and trace filtering processing. Meanwhile,according the echo power received by the main channel and the auxiliary channel,automatic gain control is performed to improve the accuracy of angle measurement of the jammer. The application results show that the jammer can be stably tracked with a high precision using the method.
