摘要
数字阵列雷达是一种接收和发射波束都以数字方式实现的全数字相控阵雷达。由于数字处理所具有的灵活性,数字阵列雷达拥有许多传统相控阵雷达所无法比拟的优越性。本文对数字阵列雷达及其研究进展进行了评述,主要介绍数字阵列雷达的基本原理、关键技术、研究进展,并对数字阵列雷达的应用前景进行了分析,提出了数字阵列雷达发展应考虑的一些问题。
Digital Army Radar （DAR） is a fully digitized phased array radar in which digital beamforming techniques is used both ha receiving and transmitting. Because both transmit and receive beamforming is 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.
