摘　　要：为解决雷达测量信息受地、海杂波的强烈干扰,导致雷达俯仰角测量难以构成有效闭环,目标俯仰角信息超差严重,并通过坐标系变换,向目标各维坐标传导超差信息的问题,该文综合考虑地、海杂波对方位角和斜距信息影响较小,以及海上靶场雷达测量网的布站特点,提出了一种利用多台雷达共有段落的方位角和斜距信息,构建联合处理模型,解算目标弹道的方法。数据测试证明,该方法可以有效解决雷达部分测量信息超差问题,提高靶场雷达测量数据处理的精度和可靠性。The radar measurement is interfered by the clutter of earth and sea,and the measurement of pitch angle is difficult to form an effective closed-loop,and the pitch angle information seriously exceeds the error tolerance,and transmits the error to every coordinates of the target through coordinate transformation.Aiming at this problem,the features of the radar distribution of sea range and the earth were taken into account,as well as the problem that the sea clutter information has less affect on azimuth and slope,and a combined processing model and algorithm were presented based on the common section of azimuth and slope information of multiradar.Test data show that this method can effectively solve the radar partial measurement information error tolerance problems and improve the precision and reliability of data processing of the measurement in sea range.
