<p><P>PROBLEM TO BE SOLVED: To provide a sheet for detection work with which a work load on an operator of an underground radar can be reduced at low cost, and an underground radar system using the sheet for detection work. <P>SOLUTION: An underground radar 11 comprises an electromagnetic wave transmitting section which transmits electromagnetic waves toward underground and an electromagnetic wave receiving section which receives reflection waves of the transmitted electromagnetic waves. On a sheet member 2, measuring lines 5 for moving the underground radar 11 are drawn in a lattice shape. In at least one end of each of the measuring lines on the sheet member 2, a positional information medium 3 is provided which has positional information of that point. The positional information is read by a reading section 12 which is provided in the underground radar 11. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
