摘　　要：靶场试验测试过程中,遥测地面站在航落区独立进行测试任务时,针对目标实际飞行弹道与理论飞行弹道之间的时空误差不断增大,导致遥测地面站丢失目标后无法进行二次捕获的问题,提出了一种基于遥测跟踪信息的同站自引导方法。该方法使用遥测跟踪信息与理论弹道空间位置信息,反算目标实际飞行时空位置,采用卡尔曼滤波算法,对目标飞行时空位置进行预测,引导遥测天线跟踪测试目标。通过试验验证,该方法可以大幅提高遥测地面站丢失目标后的二次捕获能力。The telemetry ground station can complete the test mission independently in the landing area during the range test.However,the telemetry ground station that missing targets cannot be captured-recaptured along with the increasing spatiotemporal error between the actual and theoretical flight trajectory.This paper proposes a self-guidance method at the same station based on the telemetry tracking information.The acual target flight spatiotemporal positions are derived by use of the telemetry tracking and theoretical trajectory space position information.The target flight spatiotemporal positions can also be predicted to guide the telemetry antenna tracking through the Kalman filter algorithm.Finally,test results are used to verify the substantially increasing recapture effectiveness after targets lost by the telemetry ground station.
