摘要/Abstract

摘要：

着眼解决复杂城市环境中非通视条件下的无源定位问题, 提出了一种基于概率累积的无源定位方法, 将多个三点测量系统得出的辐射源位置分布概率进行累加, 取累加后概率的极大值处作为对辐射源位置的最终估计。仿真结果表明, 此方法中接收机本身的定位精度对定位结果的影响不大, 仿真区域内几乎所有辐射源的定位误差均小于30 m, 平均测量偏差为19.4 m, 证实该方法具有一定可行性。

关键词: 概率累积, 非通视, 城市环境, 无源定位

Abstract:

To solve the problem of passive localization under not line of sight (NLOS) in complex urban environment, a passive localization method based on probability accumulation is proposed. The distribution probabilities of transmitter location obtained by multiple 3-point measurement systems are summed, and the maximum value of cumulative probability is taken as the final estimation of transmitter location. The numerical simulation results show that the positioning accuracy of the receiver has little effect on the positioning results. The positioning error of almost all radiation sources in the simulation area is less than 30 m, and the average measurement deviation is 19.4 m.

Key words: probability accumulation, not line of sight (NLOS), urban environment, passive localization
