Description

Technical Field

[0001] The utility model relates to the technical field of radars, in particular to a radar shell with wave-transmitting and wave-absorbing functions. Background Art

[0002] Laser radar is a radar system that detects targets by emitting laser beams. The working principle of laser radar is as follows: the laser radar emits a light signal to the target to be detected and receives the echo signal reflected from the target, and then compares the received echo signal with the emitted light signal. After processing and calculation by the internal computer, the relevant information of the target to be detected can be obtained, such as the target's distance, azimuth, intensity and other information. Furthermore, the various information obtained can be used to detect, track and identify the target.

[0003] Laser radar usually consists of three parts: circuit part, optical path part and mechanical structure. The existing radar outer shell is usually painted with a mixed coating of absorbent and polymer materials to improve the radar's wave absorption and wave transmission functions. However, during use, due to the special nature of light, obstructions on the optical path will cause the optical signal to attenuate, thus affecting the performance of the laser radar. In severe cases, the optical path may be completely blocked, causing the laser radar to fail to work. However, since the laser radar works outdoors for a long time, dust and other dirt will accumulate on the surface of the laser radar, which will affect the laser radar's outgoing optical signal and received echo signal.
