Abstract

The invention discloses a complex electronic system double-layer electromagnetic shielding structure with a motion platform. The double-layer electromagnetic shielding structure comprises an outer layer shielding body and an inner layer shielding compartment, wherein the outer layer shielding body comprises a cabin formed by welding a metal plate and shielding cloth used for connecting the cabin with the motion platform, the inner layer shielding compartment is welded to the inner wall of the cabin, and electric and electronic equipment capable of generating strong interference is arranged in the inner layer shielding compartment. The shielding structure has generality, through the mode of combining the metal shielding body and the flexible shielding material and additionally arranging the shielding compartment, electromagnetic interference of the electric and electronic equipment in the cabin is shielded in a double layer mode, the highest 120 dB shielding efficiency requirement of national and military standard GJB 151A-1997<requirement for military equipment and subsystem electromagnetic emission and sensitiveness> can be met, and therefore the requirement for overall shielding efficiency of radio astronomy and other high-sensitivity detection equipment can be met.

Description

technical field [0001] The invention relates to a double-layer electromagnetic shielding structure of a complex electronic system with a moving platform. Background technique [0002] In aerospace, ships, especially radio astronomy and other application fields, it is often necessary to protect complex electronic systems such as electrical cabins from electromagnetic interference. The main purpose is to prevent the interference of electronic equipment in electrical cabins from being detected by external high-sensitivity receivers, or It will affect the detection performance and effect of the system. However, the existing electromagnetic shielding structures have many problems, such as low versatility and failure to meet the shielding requirements in environments with high requirements for electromagnetic shielding (such as radio astronomy, aviation, and ships). Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present in...
