| Abstract: |
| 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. |
