摘　　要：宽带高速跳频是卫星通信对抗系统的主要抗干扰手段之一,Ka频段相控阵终端作为未来的一种重要终端站型,必须适应跳频应用的场景。针对高速跳频信号的宽带随机性,动中通载体的高机动性以及相控阵天线的扫描增益下降特性,提出在补偿波束指向偏移的基础上,基于宽带高速跳频信号的相控阵波束跟踪技术,实现Ka频段相控阵波束的高精度指向跟踪。Broadband high-speed frequency hopping is one of the main anti-jamming methods of satellite communication countermeasure system.As an important terminal type in the future,Ka-band phased array terminal must adapt to the scene of frequency hopping application.In view of the broadband randomness of high-speed frequency hopping signal,the high mobility of on-the-move carrier and the scanning gain decline characteristic of phased array antenna,a phased array beam tracking technology based on broadband high-speed frequency hopping signal is proposed to realize the high-precision pointing and tracking,on the basis of compensating the beam pointing offset.
