摘　　要：基于对干扰卫星上、下行链路的可行性分析,研究了一种空间连接型宽带干扰机。该装置主要从连接模块和干扰模块的结构和功能方面进行了设计。具体来说,连接模块连接到卫星表面,解决了远距离信号传输的功率损耗问题,实现了装置的小型化;干扰模块通过发射宽带噪声信号,实现了对微波全频段(100MHz～18GHz)卫星上行链路及其转发器的阻塞式干扰。根据卫星通信系统的特点,对该装置的干扰性能进行了分析。通过地面实验验证了该装置的连接功能。The paper researches a spatial connecting broadband jammer based on the analysis of feasibility of jamming on uplinks and downlinks of the satellite. The device is designed mainly from the structure and the function of connecting module and jamming module. Specifically, the connecting module＇s join to the satellite avoids the power loss arising from remote signal transmission, realizes the miniaturization of the device. Through the transmission of the noise signal, the jamming module realizes the barrage jamming on uplinks and transponders of the satellite whose signal frequency is among 100MHz - 18GHz. According to the characteristics of satellite commu- nication system, the jamming performance of the device is analyzed. The connecting function of the device is validated by ground experiment.
