  • 摘要: 与传统的相控阵只形成方位角依赖性的发射波束不同,频控阵通过在阵元间采用一个小频差来实现波束的自动扫描功能。频控阵能够形成具有距离依赖性和时变性的发射波束,克服了传统相控阵阵列因子不包含距离和时间变量的缺点,因而带来很多独特的应用优势。该文在作者的“频控阵雷达:概念、原理与应用”(《电子与信息学报》,2016, 38(4): 1000–1011)基础上,简要介绍频控阵雷达的基本原理,全面梳理近3年来国内外关于频控阵雷达技术及其应用方面的最新研究进展,讨论几种新的频控阵雷达技术应用前景,主要包括雷达对抗和雷达-通信一体化应用,并指出目前亟待研究解决的波束时变性、有效接收机设计、自适应信号检测与估计和原理样机研制等几个关键问题。
