Abstract :
A novel 2D direction finding algorithm for noncircular signals using two parallel linear arrays called extended rank reduction (ERARE) algorithm is presented in this paper. The proposed method needs only 1D search for joint azimuth and elevation estimation. The 2D angles estimated by ERARE are paired automatically. The estimation precision of 2D angles by ERARE algorithm is better than the DOA matrix (DOAM) algorithm which is also a 2D direction finding algorithm with dual parallel subarrays.
