| 摘 要： | 分析透明转发器的非线性特点,由于透明转发器存在“功率掠夺”现象,将星上处理同宽带跳频相结合己成为卫星抗干扰通信系统的发展趋势。军事卫星通信系统中,宽带跳频是一种应用广泛的抗干扰手段,有着十分重要的地位,这对于基于透明转发器的军事卫星通信系统抗干扰研究及商业卫星的军事应用都具有重要意义。

| Abstract: | In this paper the nonlinear characteristics of transparent repeaters. Because of the " power - probing " effect of a "bent-pipe" repeater, some onboard processing methods are needed to resolve this problem. In the MILitary SATellite COMmunication (MTLSATCOM) systems, wideband Frequency - Hop (FH) techniques plays a more and more important role. The paper is helpful both for the studies of military satellite communication anti-jamming and for the use of commercial satellite communication system for military purposes. |
