Radar vehicles are generally used in various military activities as indispensable equipment for troops to complete tasks such as information collection, target detection and tracking. When the vehicle-mounted radar works, strong electromagnetic radiation can be generated to seriously threaten the physical and psychological health of fighters in the cockpit, so that the fighting capacity of troops is reduced. Therefore, electromagnetic protection of the radar vehicle cockpit is required.
The radar vehicle cockpit is mostly made of metal materials and can shield electromagnetic waves, but the vehicle window is made of non-shielding glass and does not have an electromagnetic shielding function, and the sealing rubber strip adopted in the gap at the vehicle window is a common rubber strip and does not have an electromagnetic sealing function, so that the electromagnetic waves enter the cockpit from the vehicle window.
Therefore, improvements have been made to this, thereby improving the shielding effect; for example, CN 108215727 a, "a vehicle electromagnetic shielding window and a special vehicle using the same" discloses a vehicle electromagnetic shielding window, which mainly adopts screen sandwich type shielding glass, and realizes the conductive connection between the shielding screen in the screen sandwich type shielding glass and the window frame.
CN 105751873A "a car window shielding structure" discloses a car window shielding structure, with the glass card in the C type frame that has spread the copper mesh, not only reached electromagnetic shield's effect, but also realized the double sealing effect.
CN 207955281U, "engineering machinery cab with electromagnetic shielding function", discloses a shielding cab with electrical continuity, achieving the purpose of anti-electromagnetic radiation and anti-electromagnetic interference.
However, the screen sandwich type shielding glass used in the above is expensive to manufacture and complicated to operate practically, so that its application range is limited.
