Abstract

The invention discloses a wind profile radar rainfall and non-rainfall adaptive detection system and method. The system comprises system control module, a signal processing module, a digital intermediate frequency receiver plate, an industrial control computer, a data terminal computer and a data processing module. The system control module controls the atmosphere wind field detection process. The digital intermediate frequency receiver plate receives a radio echo signal and obtains domain signals in digital processing. The signal processing module processed the domain signals into atmosphere wind field power spectrum signals. The data processing module processes and analyzes the atmosphere wind field power spectrum signals and automatically configures corresponding detection parameters. The established adaptive detection system automatically determines whether there is rainfall or not and configures corresponding detection parameters in the detection process through a wind profile radar, so that the adaptive detection of the atmosphere wind field in rainfall or non-rainfall weather is achieved, the atmosphere wind field information under different weather conditions can be accurately measured, and better application in meteorological research and weather forecast is achieved.

Description

technical field [0001] The invention relates to the field of atmospheric wind field detection, in particular to an adaptive detection system and method for a wind profile radar with and without precipitation. Background technique [0002] Wind profiler radar is an important part of the upper-air detection system in the 21st century. At present, the wind profiler radar data has entered into commercial application all over the world, and my country is also constructing the wind profiler radar observation network. The wind profile radar has the advantages of high temporal and spatial resolution and high precision, and adopts an all-weather unattended detection method. With the popularization and application of wind profiler radar, a large amount of observation data under various weather conditions have been obtained. In order to study the characteristics of atmospheric wind field in depth, meteorological researchers have higher and higher requirements for the accuracy of observ...
