摘要
研究了任务中出现的雷达测量时标误差现象,用数据比对及差分法对该问题进行分析,采用面积及残差方差最优的方法确定时标误差的采样点数,利用提出的方法分析并解决了跟踪雷达测量数据可能出现的时标误差问题,验证了方法的正确性和有效性.
The paper studies timetag error in radar instrumentation missions. Data comparison and differential method are proposed for analysis of the problem and optimized area and residual error variance method is used to determine the sampling points for timetage error. The method is also used to analyze and solve possible timetag errors in the instrumentation data of tracking radars and to verify the correctness and efficiency of the method.
