  • Heat source detection device
    Patent number: 11933673
    Abstract: A heat source detection device is a heat source detection device that detects a heat source on the earth using observation data of a radiometer provided in a geostationary satellite and includes: a calculation unit that calculates a heat source proportion value indicating a proportion of a wavelength distribution due to the heat source included in the observation data to the observation data by curve fitting using Planck's law; and a determination unit that determines presence or absence of the heat source according to the heat source proportion value calculated by the calculation unit.
    Type: Grant
