卫星通信由于其覆盖面积广,不受距离和地理条件限制,组网灵活,频带宽,容量大,能适应业务量和网络结构变化等优点,已成为现代通信领域中重要的通信手段。但卫星通信中存在的干扰问题,影响卫星通信的质量。一、卫星通信中干扰的种类及降低干扰的一般方法1.邻星干扰卫星对其他相邻卫星产生的干扰,即卫星网之间的干扰,称为邻星干扰。产生邻星干扰的原因是,由于卫星通信间的轨位间距缩小,而引起邻星相互干扰,干扰的大小由天线旁瓣特性决定。天线辐射的
Satellite communication has become an important means of communication in the field of modern communications due to its wide coverage, freedom from distance and geographical constraints, flexible networking, wide bandwidth, large capacity, adaptability to changes in traffic volume and network structure. However, the problem of interference in satellite communications affects the quality of satellite communications. I. Types of Interference in Satellite Communication and General Methods of Reducing Interference 1. Neighboring Satellite Interference Interference with other neighboring satellites, that is, interference between satellite networks, is called adjacent satellite interference. The reason for adjacent satellite interference is that due to the narrowing of the orbital space between satellite communications, adjacent satellite interference is caused. The size of the interference is determined by the antenna sidelobe characteristics. Antenna radiation
