Research on Noise Suppression Jamming of Tracking and Data Relay Satellite System

摘要

Aiming at the weak safety protection of relay satellite system, the possible jamming platform and jamming entry path are studied, and a method of suppressing jamming of partial band noise is proposed. Firstly, the feasibility of different nodes of relay satellites may be affected by the jamming from space-borne, space-based and ground-based platforms. For the wideband noise jamming covers a wide frequency band, it is easy to affect the other spacecraft's work, and the jamming power utilization is limited. Partial band noise jamming is proposed. The jamming energy is mainly concentrated on the current communication channel of the target signal, so as to improve the perturbation and the utilization of jamming energy; through the broadband noise and partial band noise jamming simulation experiments are conducted to verify the effectiveness of the proposed method.
