DOA Estimation Performance Simulations and Analysis With Velocity Errors for A Passive Synthetic Array Using Single Moving Sensor

摘要：

　　A passive synthetic array(PSA)using a single moving sensor is formed to estimate direction of arrival(DOA).And the signal model with velocity errors is constructed.By using MUSIC algorithm,the angle estimation performance is analyzed through numerical simulations under different velocity errors.With the increase of velocity error,resolution and accuracy of multi-target angle estimation decline gradually.When errors get 10 m/s,angle estimation cant be distinguished clearly.According to the simulation result,the velocity error should not be more than 3m/s,otherwise it will cause great negative effects on the performance of multi-target angle estimation.
