综观卫星通信干扰技术的发展,卫星通信系统受到电磁干扰主要是上行干扰和下行干扰这两方面的威胁,其中上行链路可能遭受的电磁干扰威胁包括地基干扰(固定式和移动式)和干扰卫星的干扰,下行链路可能受到的干扰来自低轨道卫星干扰和飞机干扰。卫星通信系统必须采取有效的抗干扰措施以增强其电子生存能力,而采用跳频技术的卫星通信系统可以提供安全可靠的通信链路。 Looking at the development of satellite communication interference technology, the electromagnetic interference suffered by the satellite communication system is mainly caused by the uplink interference and the downlink interference. The possible electromagnetic interference threats to the uplink include ground-based interference (fixed and mobile) and interfering satellites The possible interference from the downlink is from low-orbit satellite interference and aircraft interference. Satellite communication systems must take effective anti-jamming measures to enhance their electronic survivability, while satellite communication systems using frequency hopping technology can provide a secure and reliable communication link.
