摘要
研究了TVM制导下的数据融合算法。常用的点迹融合算法是基于测量数据统计加权的融合算法,其权系数在整个融合过程中固定不变。根据TVM制导体制的特点,该文对上述算法进行改进,考虑了目标与测量设备之间的距离对加权系数的影响,在系统整个跟踪导引过程中,各传感器的加权系数随其与目标距离的改变而改变。仿真实验表明,使用文中提出的算法,在TVM制导体制下,能够取得较好的观测数据的融合效果。
The data fusion algorithm used in TVM guidance is studied in this paper. The normal plot fusion method needs to calculate weight coefficients from the measurements, and the weight coefficients are constant in data fusion process. In order to be used in TVM guidance, the data fusion algorithm is improved, and the distance between target and measurement device is considered in calculation of weight coefficients. In tracking and guiding, the weight coefficients will change with the distance between target and measurement device. By simulation, satisfactory fusion resuhs are obtained using the improved method in TVM guidance.
