利用多照射源的单站多目标无源定位

Multiple Target Location by Single Station Using Multiple Illuminators

提出一种针对多目标的单站无源定位算法,综合利用多个外部照射信号,基于对信号多径时延的测量,在目标位置空间进行概率融合,将多目标定位问题转化为对一个目标函数的多峰寻优问题。该算法通过空间关联性实现参数自动配对,能依据单次观测数据对较大数量的散射体目标同时定位。

This paper proposes a new passive location algorithm in the context of multiple external illuminators and single observer to locate multiple targets. Based on the time delays of arrival （TDOAs） of multipath signals from different illuminators, the algorithm fuses the probability in target position space and then transforms the multi -target location into a problem of multimodal optimization on an objective function. It pairs the parameters automatically according to the spatial association, which makes it possible to locate large numbers of targets simultaneously based on the measurement in single observation period.
