摘　　要：频控阵是近年来提出的一种新体制阵列技术。与传统相控阵不同的是,频控阵通过在不同通道附加很小的频偏,使其波束图在远场成为随位置、角度和时间变化的函数。频控阵这种新波束的特征产生许多新的功能,具有很多独特的应用优势和广阔的发展应用前景。首先介绍了频控阵发展历程和基本原理,然后分析了频控阵技术实现难点,最后指出了频控阵可能的应用和发展方向。Frequency diverse array（ FDA） is a new array technique proposed in recent years. Unlike con-ventional phased array,frequency diverse array uses a very small frequency shift across its array elements to provide a beam pattern which focuses direction changes as a function of the range,angle and time in the far-field. This new beam property offers many promising advantages for communication,radar,interference countermeasure applications and so on. This paper introduces the development progress and principle of fre-quency diverse array,analyzes the existing technical challenges of frequency diverse array and finally dis-cusses the promising applications and future developments.
