Abstract

Disclosed is a radome, a method of manufacturing the radome, a vehicle radar sensor, and a method of manufacturing radar. According to the embodiments, the radome comprises a radome material comprising a first region to penetrate a transmission signal and a second region to penetrate a reception signal; and a depression formed in a side of the radome material facing a position from which the transmission signal is transmitted, among sides of the radome material.

Description

technical field [0001] The present invention relates to a radome for a vehicle radar sensor and a manufacturing method thereof, a vehicular radar sensor including the radome, and a method for manufacturing the radar. Background technique [0002] Conventionally, a radome is a cover placed on the radar antenna to reduce the wind pressure on the radar antenna or damage to radio wave radiation due to weather deterioration such as snow and rain. [0003] When such a conventional radome is provided to a radar, the radar radiates radio waves using the main lobe and side lobes in the pattern of the directional beam antenna. [0004] As an example, Korean Patent Publication No. 10-1175745 (2012.08.14) discloses a vehicle radar device for rear detection using a main lobe and a side lobe, which emits the main lobe and the side lobe according to the frequency through a time slot, and its detection method. [0005] However, conventional vehicle radar devices for rear detection using m...
