Method of Fusion Algorithm in Measuring Element of Short Baseline Interferometer and Range Rate

短基线干涉仪与脉冲雷达(或微波统一测控系统)相结合的外弹道测量体制是目前航天发射任务主动段测控的主要手段。针对不同传感器跟踪测量数据的融合问题,建立了短基线干涉仪测量元素与雷达测量的距离变化率测量元素融合的算法,实现了利用测速数据确定目标的位置和速度参数的功能。仿真结果表明,该方法改变了以往短基线干涉仪测量必须依赖定位数据的境况,拓展了外弹道的数据处理手段。

External trajectory measurement system with the combination of the short baseline interferometer and radio detection and ranging （unified microwave system） is the main means of TT＆C in boost phase. Aiming at the problem of data fusion, fusion algorithm that short baseline interferometer measurement element is effectively fused with the range rate measurement of the radio detection and ranging measurement is established, the target location and flying speed parameters can be determined by velocity measurement data. The method offers a new technical means to change the situation that the short baseline interferometer measurement must rely on the target location data, and provides technical support to process external trajectory measurement.
