Study on a tracking distance estimation algorithm based on range continuous wave radar

提出一种靶场导弹飞行试验前连续波雷达跟踪不同直径目标的跟踪距离预估算法。算法利用已知外形尺寸、直径的目标类型跟踪数据结果,通过简化雷达方程,获取目标平均散射截面估计参数()及平稳跟踪段测试点信噪比参数,通过雷达实际跟踪试验数据证明跟踪距离预估计算法的准确性。该算法可有效估计雷达跟踪不同外形、直径目标的距离范围,估计误差比可控制在10%以内,可为靶场外弹道测试前雷达选型与布站、制定跟踪策略、测试方案评估及测试精度预评价等方面提供依据。

Aiming at the problem of estimate tracking distance for continuous wave radar tracking targets with different diameters before missile flight tests in the range,we propose a tracking distance estimation method based on the continuous wave radar equation,which can solve the problem of estimating the tracking distance of continuous wave radar before external ballistic testing in the range.The algorithm utilizes tracking data results of target types with known external dimensions and diameters,and then simplifying the radar equation,we can obtains the estimated parameters of the target’s average radar cross section(RCS)and the signal-to-noise ratio parameters of the test points in the stationary tracking segment.And finally,the accuracy of the tracking distance estimation algorithm is verified through actual radar tracking test data.The results show that this algorithm can effectively estimate the distance range of radar tracking targets with different shapes and diameters,and the estimation error ratio can be controlled within 10%.The estimated results can provide a basis for radar selection and station layout,customized tracking strategies,testing plan evaluation,and pre evaluation of testing accuracy before external ballistic testing in the range.
