Anemometry method and anemometry device of northern dipper sounding unit of aerological sounding

Abstract

The invention relates to an anemometry method of a northern dipper of aerological sounding. The method comprises the following steps: receiving a northern dipper satellite signal, and inputting the signal into a signal amplifier by a northern dipper signal receiving antenna in a northern dipper sonde and a receiver; amplifying the northern dipper satellite signal and sending the signal to a correlator by the signal amplifier to acquire the delay time of the signal emitted by a northern dipper satellite from the northern dipper satellite to the northern dipper signal receiving antenna and the receiver; carrying out altitude computation by a northern dipper anemometry unit directly; obtaining the real-time potential height of a northern dipper anemometry unit by the combined computation of the temperature, the humidity, the air pressure and injection initial altitude which are obtained by real-time sounding in the northern dipper sonde, and converting the real-time potential height into a height so as to realize the real-time altitude computation of the sonde; and realizing the positioning information of the northern dipper receiver of the sonde by the attitude obtained by combining the real-time computation of the temperature, the pressure and the humidity in air, and sending the positioning information to a singlechip to obtain the position and the wind speed of a northern dipper anemometry sounding device in space.

Description

technical field [0001] The invention relates to a high-altitude meteorological detection method and a detection instrument thereof. Background technique [0002] The radiosonde is a telemetry instrument, which can convert the directly sensed meteorological element values ​​into radio signals and send them to the ground. As a result, with the cooperation of corresponding positioning equipment, upper-air wind data can be obtained simultaneously. [0003] For different upper-air meteorological detection systems, the methods of aerial wind detection are different. The current high-altitude detection mainly includes high-altitude meteorological detection radar, radio theodolite, radio navigation, optical wind theodolite and other methods. [0004] At present, there is no ranging device on the wind measuring radar and the radiosonde supporting the radio theodolite used in business. The wind measuring radar must emit high-power electromagnetic waves to obtain the balloon slant di...

Problems solved by technology

[0007] Using satellite-based navigation to measure wind requires independent positioning function. At present, my country's Beidou satellite-based navigation system relies on double-star positioning and geographic elevation to determine the position. After leaving the ground, the position cannot be determined, and it cannot be used for air wind detection.
