利用雷达测速测元与新型跟踪测量设备——高精度多测速系统的距离和变化率测元进行有效融合,通过基于最小化误差平方的基础上寻找数据测元的最佳匹配,并对线性化后的测元数据进行补差,不仅实现了同时确定飞行目标的位置和速度参数,摆脱对定位数据依托的窘况,而且计算结果更为符合实际。该方法的实现,扩充了外弹道的数据处理技术手段,为分析和评价运载火箭飞行性能提供了技术支持。

By effectively fusing the measuring element of radar measurement with the range sum rate of high precision multi-velocity-measuring system, a new type of tracking equipment, target location and velocity parameters can be determined simultaneously and the dependence on the location data could be broken. Following this fusion method, the target location can be determined once the flying speed is known. The method offers a new technical means to process ballistic curve data and provides technical support for analyzing and evaluating rocket flight performance.
