| 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。 |

| Abstract: |
| Frequency diverse array（FDA） is a new array technique proposed in recent years. Unlike conventional 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 frequency diverse array,analyzes the existing technical challenges of frequency diverse array and finally discusses the promising applications and future developments. |
