【摘要】 论文主要研究了红外阵列无源定位技术。首先介绍了组合定位系统的工作原理，并研究了具有抗反辐射导弹能力的多传感器系统结构，在此基础上主要进行了两方面的工作： ·分析了基于两站的三维定位算法，推导了定位误差公式，研究了各种因素对定位精度的影响，提出了基于三(多)站的三维定位算法：加权最小二乘法和极小化误差法，并分析了定位精度。 ·对被动式多传感器多目标的数据关联进行了研究，提出了一种基于聚类的数据关联算法。 仿真结果表明，红外阵列无源定位具有较高的精度，基于聚类的数据关联算法具有良好的性能。更多还原

【Abstract】 Passive location technique for infrared array is discussed in the paper. The principle of combinated location system is presented first. Then the frame of multi-sensors system that can resist anti-radiation missiles is investigated. On the basis of the above, the following works are focus on in this paper.The algorithm based on two stations and accuracy of 3D passive location withinfrared array are analyzed with formulae. The effects of many factors on locationaccuracy are compared. Two 3D location algorithms based multi-sensors are presented. Data association used in passive multi-sensors multi-targets is investigated anda data association algorithm based on cluster is presented.Simulation results show that 3D passive location with infrared array possesses better location accuracy and indicate the upstanding performances of the data association algorithm based on cluster.更多还原
