With the fact that the precision homing of depth charge is influenced by the accuracy of angle and range estimation，and in order to study the whole-process algorithm of homing，we adopted beam domain correlation to conduct the angle and range estimation performance study of homing algorithm in the homing process of depth charge. First，we analyzed the feasibility of the method，and confirmed the effective reverberation suppression ways under the background of noise. Then assuming the moving trace of depth charge and its initial location relative to the target，the azimuth between charge and target and pitch angle of the target during the motion process are calculated according to geometric situation，and the charge rotation is simulated by adding some random errors. Finally，the azimuth and distance of target in the whole homing process are simulated and calculated. The results are basically consistent with the originally setting parameters，which verifies the correctness of beam domain correlation method.
