Abstract

Direction finding cross location is a widely used passive location method, featuring omni-direction and fast speed. However, with the increase in station number, false location points are seen to be rapidly increased among the direction finding lines. In order to accurately and rapidly locate radiation sources, how to rapidly eliminate false points is an important issue urgent to be solved. This paper proposes a cluster-based passive direction finding cross location method, which can obtain location estimates of radiation sources without acquiring any prior information about the radiation sources other than the azimuth information of the radiation sources measured by the stations. This method proves extensively applicable.
