PURPOSE:To achieve the imaging of the position of an embedded object at a high speed with high accuracy by shortening the processing time of a position detector, by operating the curve corresponding to the inclination of the locus curve of the embedded object obtained with the scanning of a radio wave emitter and a reflected wave detector and increasing the memory content to said curve to display the result thereof. CONSTITUTION:The signal from an oscillator 10 is guided to an antenna 12 through a circulator 11 to emit a radio wave. The reflected wave from the embedded object 2 under the ground 1 is detected by the antenna 12 to be inputted to an operator 15 through the circulator 11, an amplifier 13 and a sampling apparatus 14. The output of the scanning position detector 16 of the antenna 12 is inputted to the operator 15. CPU15 calculates the tangential line of the locus curve of the embedded object to calculate the inclination thereof and calculates reflected light paths to calculate the position of the object as the intersecting point of one or more of reflected light paths. By performing this calculation at plural points, the memory content at the position where the object is present is increased. Said memory content is modulated in its intensity and displayed on a display device 17 and the position of the object is discriminated from the image thereof. |
