本文主要介绍了一个自适应波束形成器的原理及其实现方法，结合当今最先进的可编程芯片，包括数字信号处理器(DSP)，现场可编程逻辑门阵列(FPGA)实现了数字波束形成，适用于如3坐标雷达系统等复杂阵列信号处理系统。其研制成果已应用在多部相控阵雷达中，缩小了我国在这个领域与其他国家之间的差距，具有重要的经济意义和军事意义。-This paper describes an adaptive beamformer principle and implementation method, combining the most advanced programmable chips, including digital signal processors (DSP), field programmable gate array (FPGA) implementation of the digital beam forming, applicable to systems such as the three coordinate complex array of radar signal processing system. Its R &　D results have been used in multiple phased array radar, the narrowing of China and other Guojia in this field between the gap and the economic significance with Zhong Yao military significance.
