Abstract

The invention relates to a method and a system for millimeter wave cloud radar three-dimensional wind field retrieval. The method comprises steps: a millimeter wave cloud radar is controlled to carry out meteorological target detection in a PPI scanning mode with a preset pitch angle, signal processing is carried out on target detection data, and original radial speed data are outputted; the original radial speed data outputted by the signal processing module are acquired, and the data are packaged and then transmitted to a main control module; the original radial speed data after being packaged are stored; the original radial speed data stored in the main control module are read and pretreated, and radial speed data for three-dimensional wind field retrieval are obtained; and the radial speed data for three-dimensional wind field retrieval are read, a retrieval equation is built under a preset solution criterion for carrying out three-dimensional wind field retrieval on the corresponding target detection data, and the three-dimensional wind field speed data are obtained. Thus, the problem that a three-dimensional wind field product can not be obtained effectively and precisely by using the millimeter wave cloud radar can be solved.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a method and system for inverting a three-dimensional wind field of a millimeter-wave cloud radar. Background technique [0002] Wind field information is one of the main meteorological factors for atmospheric sounding. Meteorological support for large-scale events, airport meteorological support, and weather forecasting all have a strong demand for fine observation of wind fields. In addition to direct measurement of wind by instruments such as anemometers and wind profile radars, indirect measurement of wind field information using tracer particles (such as cloud droplets, raindrops, smoke, etc.) floating in the air is also an important method. For this reason, weather radars currently in operation have taken wind field retrieval information as a routine output product. [0003] However, there are many deficiencies in the three-dimensional wind field retrieved by weather radar,...
