摘要
从相控阵雷达波束形成原理逐步引出了数字波束形成技术,并就其数字配相和幅度加权进行了详细的数学分析。给出了一种数字波束形成器的实现结构,也客观地指出了目前在工程实现中仍需注意的一些问题。
The digital beam forming technology is introduced based on the principle of beam forming of phased array radars. Its digital phase matching and amplitude weighting is mathematically analyzed in detail. The implementation of a digital beam former is presented. At the same time, some issues need to be paid attention to in practical engineering are pointed out.
