Description

Technical Field

[0001] The utility model relates to the field of portable laser radars, in particular to a portable laser wind measuring radar used for airborne guidance. Background Art

[0002] my country has a vast territory, with high terrain in the west and low terrain in the east, and a stepped distribution. The terrain is complex and changeable. These places are usually sparsely populated and have inconvenient transportation. For the Chinese People's Liberation Army Air Force, there is a real need for long-distance delivery of personnel, equipment, and materials for daily parachute training, outpost material support, mountain / disaster rescue, wartime mountain warfare, occupation of key strongholds, island and reef competition, island landing operations, and logistics supply.

[0003] How to quickly and accurately complete the airdrop mission is affected by many factors, such as wind speed and direction, aircraft altitude, aircraft speed, flight direction, unloading time, parachute type, airborne troops' own skills, ground command and guidance, etc., among which wind has a huge impact. Excessive wind speed will not only blow equipment and parachutists out of the scheduled landing point and deviate to dangerous areas such as power lines, roofs, and woods, but also increase the impact of landing and increase the risk of parachutists falling and fractures. Therefore, before combat, the local wind speed and direction must be accurately measured to eliminate safety hazards.

[0004] In the field of laser wind radar, wind radar can obtain atmospheric wind field information and atmospheric wind field distribution based on the Doppler effect of laser. The portable laser wind radar equipment can be carried by airborne guides to the parachute destination to monitor the wind field information in the area and provide accurate wind field data for soldiers who perform subsequent parachute missions.

[0005] Currently, there are two common ways to measure wind during airborne training.

[0006] 1. Use a simple and lightweight mechanical wind speed and direction meter. Although it is easy to use, it can only measure wind field information near the ground, and has low resolution and large measurement errors, and cannot reflect the real wind field environment above the landing site.

[0007] 2. Use weather balloons. Release the balloons two hours before the parachute jump and transmit the measured wind speed and direction information back to the command center. However, there are problems such as long preparation time, pollution, danger, and high cost. Utility Model Content
