在航迹融合问题中,以往的次优航迹融合算法和互协方差融合算法存在融合时间和融合精度的矛盾问题.提出了一种基于变结构多模型思想的航迹融合自适应切换算法,用以解决航迹融合过程中存在的计算量和融合精度之间的矛盾.该算法根据切换规则自适应地选择具体的航迹融合算法以优化计算时间.仿真结果表明,该算法在保证融合精度的前提下节省了融合计算时间.

There is a contradiction between the fusional time and fusional precision when using the former SF and WCF track fusion. A track fusion adaptive switching algorithm based on the VSMM is presented to solve the contradiction between the fusional time and fusional precision during the fusional process. It can switch between different track fusion algorithms according to a switching rule during the fusion process to optimize the calculative time.The simulation proves that this adaptive algorithm decreases the calculative quantity of the track fusion under the situation that it satisfies the demand of the fusional precision.
