摘要
PROBLEM TO BE SOLVED: To provide a combined buried material survey device, component, easy to handle, dispensing with processing for unifying an investigation result and eliminating mutual influence between one sensor and the other sensor.;SOLUTION: An antenna 20 of a buried material detecting radar sensor is disposed inside and on the same plane as a coil 10 of a metal detecting sensor so that measuring reference points 10a, 20a coincide with each other. A metal plate element 28 of the antenna has a through slit 30. Further, the antenna 20 is constituted of so-called three-element type radar antenna or the like by combining a plurality of antenna elements 22, 24, 26 having respectively different planes of polarization.;COPYRIGHT: (C)2001,JPO
