Target localization in multipath environment through the exploitation of multi-frequency array.
In this paper, we propose a multi-frequency array structure that achieves accurate target localization in a multipath environment. The use of multi-frequencies enables decorrelation in the array to operate direction-of-arrival (DOA) estimation for coherent arrival paths, whereas the spatial filtering of the signals makes the paths separable for robust range estimation. Multi-frequency radar techniques are then applied for range estimation of each path. The target position is identified by the shortest range coupled with its DOA.
