摘　　要：因基阵各通道不均衡,使得水声接收系统波束形成时,目标检测、方位估计等性能经常达不到预期。分析了各通道信噪比、辐值、相位影响波束信噪比的机理,提出了一种减小基阵各通道不均衡的方法,并利用实测数据进行了仿真。仿真结果表明:该方法可有效地提高水声接收系统的目标检测、方位估计等性能。Due to the disequilibrium of the channels in the array,it is difficult to achieve the expected performance such as target-detecting and orientation-estimating during the beamforming of acoustic receiving system.In this paper,the mechanism of signal-to-noise ratio,amplitude and phase of each channel affecting the beam signal-to-noise ratio is analyzed,a method to reduce the disequilibrium of the channels in the array is proposed,and the measured data is used for simulation.Simulation results show that this method can effectively improve the target-detecting and orientation-estimating performance of acoustic receiving system.
