| 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 propose... |
