与相控阵通过阵元之间的相差控制波束指向不同，频率分集阵列（FDA）雷达通过在阵元间引入频差的方式可以实现更高自由度的波束控制。概述了国内外频率分集阵列雷达的研究进程，重点从阵列结构及方向图解耦技术、电子反对抗技术应用、电子对抗技术应用等方面梳理并分析了FDA当前的国内外研究现状。在此基础上，针对基于解耦的FDA非时变波束控制、基于FDA的电子战技术以及基于FDA雷达实用化研究等后续亟待解决的关键技术难点问题展开分析。分析得出，要实现基于FDA的实战化应用，需要得到可行的非时变FDA距离-角度解耦波束控制方法，并开展基于FDA结构分析、发射波形设计和频控函数设计的综合应用研究，从而推进目前处于概念系统设计阶段的FDA雷达的实战化应用进程。

Different from the phased array in which the beam direction is controlled by phase difference between array elements, the frequency diversity array (FDA) radar can realize beam control with higher degree of freedom by introducing frequency difference between array elements. This paper summarizes the research progress of FDA radar at home and abroad, and analyzes its current research status from aspects of array structure and orientation graphic coupling technology, electronic countermeasure technology application, electronic countermeasure technology application and so on. On this basis, some key technical problems to be solved, such as uncoupled FDA time-varying beam control, FDA-based electronic warfare technology and FDA-based radar practical research, are analyzed. For actual combat application of FDA, it is needed to develop a feasible time-invariant FDA distance-angle decoupling method of the beam and carry out integrated application research concerning FDA based structural analysis, launch waveform and frequency control function design, so as to speed up the process of FDA radar from conceptual stage to combat application.
