Buhong Wang · Modern Defence Technology · 2010
Aimed at the problem of DOA estimation of coherent source under non stationary noise, a new differencing smoothing algorithm is presented. Then its elements and basic steps are expounded. Subspace convergence performance, angle resolution performance and DOA estimation precision are analyzed with the simulation experiment. The simulation conclusion indicates that the algorithm can eliminate non stationary complex noise. It also has the properties of low computation power, better direction finding performance and no false peaks.
