摘要
本文针对被动多传感器的量测数据关联问题,提出一种新颖的基于角度余切值的快速数据关联算法。该算法直接采用角度信息进行数据关联,不需要计算异面直线之间的距离,避免了将角度换算成距离,有效提高了计算效率。首先通过方位角与俯仰角检测对所有可能关联组合进行筛选,然后采用指示函数法对候选关联集进行分析,挑选出正确的关联组合。仿真实验表明,该算法在不影响性能的前提下,运算时间上明显少于传统算法。
In consideration of the measurement data association problem of multiple passive sensors,a novel data association algorithm based on the cotangent of angles is proposed,which improves the computing efficiency by dealing with the angle information directly,thus the conversion from angles to the distances of dissenting beelines is avoidable.Firstly,all possible associations are screened by azimuth angle test and elevation angle test,then the indicated function analysis is used to select the correct association from the set of candidates.The simulation results show that the proposed algorithm is much faster than the conventional ones without the decrease of performance.
