摘要

为了在工程中应用数字波束形成技术，本文深入地讨论了两个问题：（１）数字波束馈源，文中说明了数字波束馈源是减少设备的一种有效方法，给出了它的基本概念，并详细推导了为在主阵面得到需要的方向图时馈源所需的权值计算公式；（２）通道幅相误差的检测和校正，文中给法，该方法既适用于强迫馈电也适用于空间馈电的相控阵雷达。

Abstract

This paper discusses two topics in detail for engineering application of digital beamforming technology. （1）Digital Beamforming Feed: Digital beamforming feed is an effective way to reduce equipment. The paper presents the principle and deduces the formulae about weighting in feed for getting satisfactory patterns. （2）Test and Correction about the Amplitude and Phase Errors among Channels: A method to test errors by means of the patterns is given. It can either be used in phased array of cooperation feed

or space feed.
