Radar fire point and satellite fire point identification fusion method

The invention relates to a radar fire point and satellite fire point identification fusion method. The method comprises the following steps of: firstly, refining original data monitored by a satellite by adopting a nearest neighbor interpolation method according to the size of a 1km * 1km grid, converting radar monitoring data from a spherical coordinate system into a Cartesian coordinate system, and finishing gridding; secondly, carrying out time matching on the radar data and the satellite data under different time resolutions, after time and space are aligned, superposing the radar data and the satellite data into a unified grid, carrying out fire point marking by adopting a loosest strategy, and marking a fire point source; and finally, further studying and judging fire points which are not distinguished by the satellite and the radar at the same time in combination with meteorological information, identifying pseudo fire points, and outputting a result. The method can be applied to large-range forest fir
