Claim:
1. A method for detecting a zonal underground target in mountain land based on ridge heat radiation correction, the method comprising: receiving an infrared energy image of terrain, the infrared energy image including the zonal underground target in mountain land; acquiring digital elevation information of terrain, comprising: performing de-noising pretreatment on the digital elevation information array as obtained in the acquiring digital elevation information of terrain; detecting a ridge line according to the digital elevation information array on which the de-noising treatment has been performed, comprising: determining an energy correction at a ridge position according to an energy distribution feature at the ridge position, and correcting the infrared energy image based on the energy correction as determined, the ridge position being determined based on the continuous ridge line as extracted; and detecting the zonal underground target in the digital elevation information array, comprising:
