摘　　要：为了对潜艇目标进行识别,提出了一种尺度识别方法。该方法根据潜艇的形状,建立了潜艇回波亮点模型,并在此基础上,采用高分辨的MUSIC算法,对潜艇目标亮点进行方位估计,从而对实现目标的尺度识别。同时采用高频CW信号作为鱼雷的主动声信号,对MUSIC方位谱进行了的仿真。仿真结果表明,该方法具有很高的方位分辨率,能够很好地实现对潜艇目标的尺度识别,具有很强的实用性。In order to realize submarine target recognition, a scale recognition method was presented. Based on the shape of the submarine, submarine echo highlight model was established, and on this basis, high resolution MUSIC algorithm was used to get the submarine target highlight DOA estimation, thus to realize the target scale identification. At the same time using high frequency CW signal as a torpedo active acoustic signal, MUSIC azimuth spectrum was simulated. The simulation results show that, this method has high range resolution, can well realize the scale of submarine target recognition, and have strong practical applications.
