摘要： 为了抑制干扰实现卫星的安全通信，首先分析了各种干扰方法对卫星跳频系统干扰的可行性，重点研究了一种新颖的干扰方法——部分驻留时间干扰对卫星跳频系统的干扰效果。在此基础上，提出了抑制部分驻留时间干扰的智能天线波束形成方法，建立了系统模型，并提出了转换矩阵的概念。仿真结果表明，该方法对部分驻留时间干扰具有较好的抑制作用，并且提高了波束指向精度及波束收敛速度。

Abstract: In order to suppress interference and achieve safe satellite communications, the feasibility of various interference methods to interfere satellite frequency-hopping systems are analysed first, mainly focusing on the interference effect of a new interference method i.e. part time-resident interference on satellite frequency-hopping systems. On this basis, a smart antenna beamforming method to suppress part time-resident interference is proposed, the system model and the concept of transformation matrix is proposed. Simulation result shows that this method can suppress part time-resident interference effectively and can improve the beam’s pointing accuracy and the beam’s convergence speed.

Key words: Satellite communications, Frequency hopping, Part time-resident interference, Interference suppression
