| Abstract: | In the paper, several typical effects of noise interference on passive sonar system are analyzed via signal processing method, which concern the key procedures of underwater passive sonar system, such as signal detection, DOA (Direction Of Arrival) estimation and system saturation. Three indices are introduced to evaluate the noise interference effects including the power ratio of signal to jammer, the error of estimated DOA and the block interference power. Simulation results that demonstrate the effect are given. |
