摘要：
In order to estimate the spatial orientation of weak signal accurately, DOA estimation algorithm for coherent weak target signal in strong interference environment was proposed. Firstly, this algorithm carried out the decorrelation of the coherent weak signal via modified Toeplitz matrix. Then, the strong interference signal corresponding to the feature vector was removed from the subspace. Finally, DOA estimation of the weak signal was accomplished by making use of MUSIC algorithm. Simulation results indicate that the algorithm can eliminate the influence of strong interference signal effectively.
