一种用于小平台的阵列虚拟阵元波束形成方法

摘要

Detection of submarine small platforms (UUV, AUV, etc.) is often limited by their own size and array deployment cannot be performed in a conventional manner. At present, most array signal processing is based on beamforming. Therefore, the size of the array aperture directly determines the performance of the target azimuth detection. In this paper, a virtual array element beamforming method is proposed, which is better than the conventional method in array signal processing of submarine small platforms.%水下小平台(UUV、AUV等)的探测方面往往面临自身尺寸的限制,而无法按照常规的方式进行阵列布放.目前阵列信号处理大多基于波束形成对其进行信号处理,因此阵孔径的大小直接决定目标方位探测的各项性能.本文提出一种虚拟阵元波束形成方法,相对于常规方法在水下小平台的阵列信号处理方面得到了较好的应用.
