| 摘 要： | 针对测向交叉定位系统研究了目标定位方法及多目标测量数据关联问题.给出了不同的目标位置求解方法,计算了不同方法目标定位精度,并对定位方案的选择提出了建议.提出了基于不变量的目标同一性识别方法,同时也分析了基于残差的数据关联方法,通过数字仿真对比了这两种方法的数据正确关联概率.仿真结果表明:基于不变量的新方法正确关联概率与基于残差的数据关联方法相当,但计算量远小于后者.

| Abstract: | Target location and measurement data association problem of detection system based on direction of arrival is researched.Dif-ferent location methods and it's accuracy are discussed,best location choice are then concluded.Utilizing invariant,a new method are proposed,meanwhile least distance data association method is also analyzed and correct probabilities of data association are offered in the end.Simulation resultsshows that correct probabilitiesofthe new methodare almostsame as the least distance methods,but calculation remarkably is reduced. |

| Keywords: | data association passive station location accuracy multi-target invariant |
