频控阵雷达技术研究进展综述

由于频控阵雷达具有距离依赖性和时变性的阵列因子，能够克服传统相控阵雷达阵列因子缺失距离变量和多输入-多输出雷达发射阵列增益损失的缺点，但是，频控阵雷达在系统理论、信号处理和应用实现等方面仍存在诸多待解决的研究问题。该文分析了频控阵雷达技术的概念、内涵与外延，梳理了近五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，论述了频控阵雷达干扰与抗主瓣干扰、模糊杂波抑制与盲速目标检测以及定位欺骗方面的应用优势，并讨论了频控阵雷达技术的未来融合化发展趋势。 

Recent Advances in Frequency Diverse Array Radar Techniques

Due to the range dependence and time-varying array factor of Frequency Diverse Array (FDA) radar, it can overcome the miss of range variable in traditional phased-array factor and gain loss of Multiple-Input Multiple-Output (MIMO) radar array. In recent years, FDA radar techniques have attracted more and more attention of researches and institutions. Nevertheless, there are still many open problems to be solved in FDA radar system theory, signal processing and application implementation. In this overviewing paper, we introduced the FDA concepts, motivation and extending techniques. The latest research advances on FDA radars and their applications are comprehensively reviewed, and the typical application prospects of FDA in jamming radar and radar anti-jamming, ambiguous clutter suppression and blind velocity target detection together with localization deception are discussed. Finally, several key research problems that need to be solved in future work are pointed out.
