Abstract

The invention discloses an airborne near-infrared laser radar system for detecting cloud supercooled water. The system comprises a laser radar host and a transceiver system connected with the laser radar host. The laser radar host consists of a pulse laser, a coupling convex lens, a light splitter, and a transceiver coupling reflection mirror, wherein the units are connected successively; the light splitter is connected with a photoelectric detector; the transceiver coupling reflection mirror is connected with a polarizing light splitting system and a first photomultiplier; the polarizing light splitting system is connected with a second photomultiplier; and the pulse laser, the photoelectric detector, the first photomultiplier and the second photomultiplier are connected with a computer control processing system. According to the near-infrared laser radar system, cloud supercooled water distribution is detected by means of laser remote sensing; and thus a problem that the cloud supercooled water threatens the flight security according to the existing airborne cloud detection technology can be solved. Compared with the existing microwave remote sensing technology, the near-infrared exiting light source with the shorter wavelength is employed, so that the cloud supercooled water detection precision is improved.

Description

technical field [0001] The invention belongs to the cross field of weather modification and laser active remote sensing, and relates to an airborne near-infrared laser radar system for detecting supercooled water in clouds. The invention also relates to the inversion of using the above airborne laser radar system to detect supercooled water in clouds method. Background technique [0002] Supercooled water in clouds is a parameter of special concern in the field of weather modification. The existence and content of supercooled water is one of the important conditions for catalyzing supercooled cloud artificial rainfall enhancement operations. one of the important indicators. In addition, the supercooled water in the cloud also seriously threatens the safety of the aircraft and can easily cause aviation accidents. [0003] At present, the cloud particle detection technology mainly adopts two methods: airborne cloud direct detection and ground-based microwave radar remote sen...
