摘要
频控阵雷达是近年来提出的一种新体制阵列雷达技术,它可以在发射天线上附加一定的频率偏移,这是与传统相控阵最大的区别。通过发射天线的频率偏移,使其波束图在远场成为随位置、角度和时间变化的函数。频控阵这种优秀的能力具有非常独特的优势,频控阵雷达不仅可以解决发射波束的角度指向问题,还可以实现发射波束的距离指向。文章介绍了频控阵雷达的概念与基本原理,并且分析了频控阵技术的难点问题和频控阵雷达在未来的应用前景。
Frequency diverse array radar is a new system of array radar technology proposed in recent years.It can add a certain frequency offset to the transmitting antenna,which is the biggest difference from traditional phased array.Through the frequency shift of the transmitting antenna,the beam pattern becomes a function of position,angle and time in the far field.The excellent ability of the frequency diverse array has a very unique advantage.The frequency diverse array radar can not only solve the angle and pointing problem of the transmitting beam,but also realize the distance pointing of the transmitting beam.This article introduces the concept and basic principles of frequency diverse array radar,and analyzes the difficult problems of frequency diverse array technology and the future application prospects of frequency diverse array.
