High precision bearing of ship's stern section based on linear additive array

提出了利用线性加法阵来高精度定向舰船螺旋桨部位的方法。设计了具体的自适应线性相位任意时延ＦＩＲ滤波器对舰船螺旋桨所辐射的高频噪声源进行了定向和定位。仿真结果表明：利用本文的方法来进行舰船螺旋桨部位的定向和定位是有效的．

A new high precision method to determine the bearing of ship's stern section by using a linear additive array is proposed. Based on a adaptive arbitrary time-delay linear phase FIR digital filtering algorithm, a simulation experiment of determining the bearing and range of high-frequency noise source at a ship's stern is done. The simulation results show that the method is effective.
