摘要
数字阵列雷达是一种接收和发射波束都采用数字波束形成技术的全数字阵列扫描雷达。由于收发波束形成均以数字方式实现 ,因而它有较好的数字处理灵活性 ,拥有许多传统相控阵雷达所没有的优良性能。本文对数字阵列雷达进行了综述 ,主要介绍数字阵列雷达的基本概念、关键技术、研究进展、潜在的应用以及未来的发展趋势。
Digital array radar (DAR) is a fully digitized phased array radar in which digital beamforming technique is used both in receiving and transmitting. Because both transmit and receive beamformings are realized in digital form,DAR has higher flexibility of digital processing and offers a number of attractive features than conventional phased array radar. In this paper,an overview of digital array radar is presented,including the basic concept,key techniques,recent progresses,potential applications and the future development.
