Abstract
In this paper, a Crossing Direction Finding (CDF) for localizations of multiple targets is proposed by using triangular theory. The location of a target is unique if the directions to other two determined points are known a priori. The two 2D direction-of-arrivals (DOAs) of target are obtained by using two cooperative radars respectively. The 2D DOAs are automatically matching by using L-shape array and conjugate-ESPRIT algorithm. The multiple targets'DOAs are automatically matching by using one reference sensor in multiple coordinate system. This method has less demand on radar system property, while hold a better resolution on localization than single radar detecting algorithm. Simulation results show that the CDF has a well performance on multiple targets localization.
