Abstract

The invention relates to a data fusion method and system of a millimeter-wave cloud radar. The data fusion method comprises the following steps of building an observation platform of the millimeter-wave cloud radar, wherein the observation platform comprises a control module, a signal processing module, an information acquisition module, a main control module and a data fusion module; controlling the radar to carry out meteorological target detection according to a multi-mode working mode by the control module, obtaining detection data and transmitting the detection data to the signal processing module; carrying out signal processing on the detection data by the signal processing module and outputting; acquiring the signal-processed detection data output by the signal processing module by the information acquisition module, and carrying out package processing on the acquired detection data and storing the processed detection data into the main control module; and carrying out data fusion on the detection data stored in the main control module by the data fusion module and obtaining a fusion result. The data fusion method has the advantages that the observation to meteorological targets in the full-height detection range is realized, the data quality and the detection efficiency are improved and the adaptability of the cloud radar to different meteorological targets is enhanced.

Description

technical field [0001] The invention relates to the technical field of positioning or presence detection using radio wave reflection or re-radiation, in particular to a data fusion method and system for millimeter wave cloud radar. Background technique [0002] The millimeter-wave cloud radar is mainly used for the detection of targets such as clouds, fog, and weak precipitation. It uses the scattering effect of small particles on electromagnetic waves to continuously measure the echo signals of meteorological targets above the site, and obtain meteorological target information with high temporal and spatial resolution. The azimuth and all-weather observation capabilities are widely used in atmospheric science research, artificial weather modification, automatic cloud observation, airport meteorological support, military meteorological support and other aspects and fields. [0003] The original millimeter-wave cloud radar adopts a single-mode observation method. Only one wor...
