A device and method for real-time in-situ wind measurement in near space

Abstract

The present invention relates to a device and method for real-time in-situ wind measurement in adjacent space. The device includes: a loudspeaker, used for transmitting sound wave emission signals; an acoustic sensor, used for receiving sound wave emission signals; a transceiver control sub-device, used for sound wave The generation and amplification of the transmitted signal and the digitization of the received signal; the data processing sub-device is used to realize the inversion of the atmospheric wind field; and the environmental measurement sensor is used to obtain the current environmental temperature, humidity and air pressure data, which is used to calculate the air temperature in the atmospheric environment. The speed of sound; the device applies the sonic wind measurement technology to the measurement of the atmospheric wind field at the height of the adjacent space, and the wind speed information can be obtained by measuring the propagation delay time of the sound wave signal from the speaker to the acoustic sensor; the device is not only easy to implement, but also stable and reliable. With high wind accuracy, it has the ability to detect wind fields with a large spatial coverage from the ground to the stratosphere.

Description

technical field [0001] The invention belongs to the technical field of in-situ detection of atmospheric wind field, and in particular relates to a device and method for real-time in-situ wind measurement in adjacent space. Background technique [0002] At present, there are many in-situ wind measurement methods on the ground, mainly including: wind cup vane, wind speed tube, hot-wire type, ultrasonic wave, piezoresistive solid-state type, and impeller type. In addition, balloonsondes, dropsondes, and rocketsondes and other near-space in-situ wind measurement methods all use sounding balloons or parachutes as wind tracers to achieve wind field measurement. However, this in-situ wind measurement method can only detect a single vertical section of the atmospheric wind field at one time, which cannot meet the needs of wind field detection with large spatial coverage. In addition, there is currently no real-time in-situ wind measurement device and method that can conduct large-s...

Problems solved by technology

However, this in-situ wind measurement method can only detect a single vertical section of the atmospheric wind field at one time, and cannot meet the wind field detection requirements for large spatial coverage

In addition, there is currently no real-time in-situ wind measurement device and method that can conduct large-scale and long-term continuous wind measurement in the adjacent space, especially at the height of the stratosphere.
