Abstract :
A single-snapshot two-dimensional direction finding algorithm is proposed based on two parallel uniform linear arrays. Two matrices with designated relationship are constructed using the received data of single snapshot, then the concept of DOA matrix method is introduced to estimate the directions of incident signals. The proposed method can deal with coherent signals. The simulation results are presented to validate the proposed analysis.
