Atmospheric temperature sounding system and method of wind profiling radar

Abstract

The invention relates to an atmospheric temperature sounding system and method of a wind profiling radar. The atmospheric temperature sounding system comprises an industrial personal computer, a data processing module, a system control module, an audio signal generator, a digital intermediate-frequency receiver board and a signal processing module. The data processing module is used for calculating audio parameters; the system control module is used for controlling the temperature sounding process; the digital intermediate-frequency receiver board is used for receiving echo signals of the radar; the signal processing module is used for processing the temperature sounding signals; the data processing module is used for processing thermogram data. The velocities of propagation of sound waves in air at different heights are sounded through the wind profiling radar, processing is performed through a mathematical model of the corresponding relation between the propagation velocity and the atmospheric temperature, and thus values of the atmospheric temperature changing along with height can be obtained. According to the method, sounding balloons do not need to be launched, continuous sounding can be performed, data are acquired in real time and are accurate, the data rate is high, and the atmospheric temperature sounding system and method of the wind profiling radar can be used for the fields of meteorological observation, air pollution monitoring, meteorological support for airports and the like.

Description

technical field [0001] The invention relates to the field of atmospheric temperature detection, in particular to a wind profile radar atmospheric temperature detection system and method. Background technique [0002] In meteorological observation, detecting atmospheric temperature is an indispensable item. The original method of detecting atmospheric temperature is realized by launching sounding balloons. In the routine business of my country's meteorological stations, sounding balloons are released at regular intervals every morning and evening to collect atmospheric meteorological elements such as wind speed, wind direction, temperature, humidity, and air pressure. Generally, this method can only obtain two sets of meteorological data per day, and the data acquisition rate is very low. There is a lack of detection data for the situation where the continuous change of atmospheric temperature needs to be monitored every day, and it is impossible to conduct research on atmosp...
