METHOD FOR RECOGNIZING BURIED OBJECT, AND BURIED MARKER

摘要

PROBLEM TO BE SOLVED: To provide a method for recognizing a buried object in which a stable operation can be realized even when the burying depth of burial is large. SOLUTION: A data carrier 2 and an intermediate body 10 for improving the quality of the receiving path of a question signal 7 from a questioner 4 to the data carrier 2 are buried in the neighborhood of a buried object 1. The question signal 7 transmitted from the questioner 4 is received through the intermediate body 10 by the data carrier 2, and a response signal 9 is transmitted by the data carrier 2, and received and demodulated by the questioner 4. Then, information can be obtained.
