Matrix Decomposition Approach for Pre Estimation of Number and Coherence of Waves

Abstract

At first, necessity of pre estimation of number and coherence of waves in direction finding of multiple emitters was noted. Secondly, the theory of matrix decomposition approach of pre estimation of number and coherence of waves was studied and the computing steps of matrix decomposition approach were given. Thirdly, some simulation experiments of pre estimation of number and coherence of waves were done based on the simulation environment. The simulation experiments show that the pre estimation results basically reveal the real situation of the waves.
