Problems solved by technology

The radiation emission generated by the common mode or differential mode current will generate an induced current on the edge of the penetration hole and the penetration component (especially the shielding layer of the radio frequency cable), and the current will generate secondary radiation to the outside of the spacecraft and be received by the receiving antenna , and finally enter the receiving system, which will affect the receiver's reception of normal signals

Abstract

The invention provides a method for inhibiting accidental radiation emission of satellite cabin passing cables. The method for inhibiting accidental radiation emission of the satellite cabin passing cables comprises the steps of bandaging of a low frequency cabin passing cable, bandaging of a high frequency cabin passing cable and bandaging of cable cabin passing openings. Through the method, the cables and the cable cabin passing openings are bandaged without changing the structure and the moving direction of the satellite cables, influence on cable temperature is small, anti-vibration effect is good, and shielding effect is good.

Description

technical field [0001] The invention belongs to the technical field of satellite electromagnetic compatibility design, and in particular relates to a method for suppressing unintentional radiation emission of a satellite penetrating cable. Background technique [0002] Cables are divided into two categories according to the frequency of the transmitted signal: low-frequency cables and high-frequency cables. Cables are common key components on satellites and are used to connect electronic instruments on the spacecraft. Low-frequency cables are mainly used to transmit signals with frequencies less than 10MHz, and high-frequency cables are mainly used to transmit signals with frequencies greater than 10MHz. They all include connectors and connecting cables, which are used to realize the transmission of high and low frequency signals on the spacecraft. [0003] In terms of spacecraft structure and layout design, due to the different functions of equipment and the special insta...
