GUIDING SYSTEM OF THREE-DIMENSIONAL HIGH-DIRECTIVITY INFRARED LIGHT FOR AIRCRAFT LANDING

摘要

A guiding system of three-dimensional high-directivity infrared light for aircraft landing and an aircraft landing guide method using same. The system comprises a low divergent infrared laser source (2) emitting at an optimal landing angle, an optical system (5) making lasers emit a directional radiation optical image, an infrared light detection system provided in aircraft, and an identification, analysis and display system (6) for optical image, the wavelength of the infrared laser emitted by the infrared laser source being at the wave band range of 3 to 5 um or 8 to 12 um. The system uses the high-directivity infrared laser and transmits the navigation information only in specific directions, hence, energy waste can be reduced, the navigable distance can be increased, and the anti-interference performance can be improved.
