Buried object detection sensor

摘要

A combined type buried object detection sensor is provided, in which a MD and a GPR are integrated to improve a detectivity. A buried object detection sensor 10 has a constitution in which plural antenna elements composing a GPR 14 are disposed on a circumference, an inner coil 16 of a MD 12 is arranged at a center portion of the GPR 14 and an outer coil 18 of the MD 12 is arranged at a periphery of the GPR 14 , the GPR 14 has slits 20 separating the respective antenna elements, and the slits 20 between adjacent antenna elements are connected by a metal leaf 36.
