This paper presents a new interference location method based on Radial Basis Function (RBF)neural network in conjunction with MBA.The proposed method can directly obtain high accurate closed form solution of DOA estimates.Therefore,it can avoid the all direction peak values searching,which is necessary for the classic high accurate DOA estimation method.Furthermore,the method is computationally effective under real time condition owing to its superior ability of parallel processing,which makes it feasible to carry out in practical interference location system.Simulation results show the effectiveness of the proposed method.
