AI Technical Summary

Technical Problem

Existing radar protective covers are prone to fogging or frost formation in low-temperature, humid, or freezing environments, which affects radar signal transmittance. They also have shortcomings in electromagnetic interference shielding, infrared transmission, and power connection.

Method used

The polycarbonate radar radome adopts a multi-layer structure, including a polycarbonate substrate, a hardened layer, an ITO film layer, an AR film layer, and a waterproof film layer. Conductive silver paste is applied to the upper and lower layers of the ITO film layer. The conductivity of the ITO film layer is used for heating and defogging. Combined with the AR film layer, the infrared transmittance and electromagnetic shielding are improved.

Benefits of technology

It effectively prevents fog and frost formation, ensures smooth radar signal transmission, enhances electromagnetic shielding and infrared transmittance, and facilitates power connection, thus extending service life.
