Title:
METHOD AND APPARATUS FOR IMPROVING LASER RANGING CAPABILITY OF RADAR SYSTEM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/116213
Kind Code:
A1
Abstract:
A method and apparatus for improving the laser ranging capability of a radar system, and a storage medium. The method comprises: obtaining the current operating temperature, a preset operating temperature range, and a center wavelength temperature change rate of a laser (S301); determining the bandwidth of an optical filter on the basis of the preset operating temperature range and the center wavelength temperature change rate of the laser, and establishing a radar system on the basis of the bandwidth of the optical filter (S302); determining the current center wavelength of the laser on the basis of the current operating temperature of the laser (S303); and when the current operating temperature of the laser is less than a minimum critical value of the preset operating temperature range, heating the laser until the current operating temperature of the laser reaches at least the minimum critical value of the preset operating temperature range (S304). According to the method, optical noise such as ambient light incident to the radar system can be reduced by maintaining the operating temperature of the laser, thereby improving the anti-interference capability and the ranging capability of the radar system.
