阵列信号处理的目的是通过对阵列接收的信号进行处理，增强所需的有用信号，抑制无用的干扰和噪声，并提取有用的信号特征及信号所包含的信息。与传统的单个定向的传感器相比，传感器阵列具有灵活的波束控制、高信号增益、极强的干扰抑制能力以及高空间分辨能力等。(The purpose of array signal processing is to enhance useful signals required by the array, to suppress unwanted interference and noise, and to extract useful signal characteristics and information contained in the signal by processing the signals received by the array. Compared with the traditional single orientation sensor, sensor array with flexible beam control, high signal gain, strong interference suppression and high spatial resolution capabilities.)
