一种同波束多目标测轨的角度修正方法

摘要

To solve the deviation of angle measurement data about multi-target orbit determination in spread spectrum mode,this paper proposes an angle correction method based on multi-target angle error voltages after analyzing its defect. According to this method,actual tracking data is analyzed and the inver-sion checking for orbit determination is completed by correcting actual angle measurement data. Results show that real-time angle correction through improving the transmission mode of multi-target angle meas-urement information can increase the multi-target measurement accuracy in same beam.%为解决船载测控设备对同波束内的非主跟踪扩频目标测轨时测角数据偏差大的问题，剖析了现有设备同波束多目标测轨方法的缺陷，提出了一种基于多目标角误差电压的角度修正方法，根据此方法分析了测控过程中获取的外测数据，对实测角度数据进行了修正和定轨反演验证，通过多目标测角信息传输方式的改进实现测角数据的实时修正，有效提高了同波束多目标飞行轨迹测量精度。
