Abstract:
A mine detector for detecting a mine buried in the ground comprising:transmitting and receiving means for transmitting an electromagnetic wave toward the ground of a range intended to detect said land mine for scanning, and receiving a reflected wave thereof; position detecting means for detecting the position of said transmitting and receiving means at a time said transmitting and receiving means receives said reflected wave; an internal ground structure information generating means for generating information indicative of a three-dimensional structure in the ground based on a period of time from the transmission of said electromagnetic wave by said transmitting and receiving means to the reception of the reflected wave, a received level of said reflected wave, and a position detected by said position detecting means; image information generating means for generating image information for display from information indicative of said three-dimensional structure generated by said internal ground structure information generating means; display means for displaying an image based on said image information generated by said image information generating means; and mode switching means for switching a first mode for instructing said display means to dispaly an image indicative of the scanned range of the ground, and a second mode for instructing said display means to display an image representative of a state in the ground, generated by said image information generating means, wherein said display means displays the image indicative of the scanned range of said ground when switched to said first mode, and displays the image representative of a state in the ground when switched to said second mode.
