Abstract:
A non-destructive probing system for non-destructively probing for a search object buried in a matrix containing dielectric material by radiating electromagnetic waves to said matrix, comprising:a probe which is disposed in opposing relation to a surface of said matrix, radiates electromagnetic waves to said matrix, and detects radar reflection signals formed by reflection of said electromagnetic waves; and a signal processor for calculating the signal reflected by the search object from said radar reflection signals, wherein said signal processor comprises: a unit for forming designated groups from said radar reflection signals; a storage for storing said designated groups of radar reflection signals individually, a first calculator for calculating a standard background signal from each of said designated groups of radar reflection signals stored individually, a second calculator for calculating a differential signal between each of said radar reflection signals and said standard background signal separately for each of said designated groups, and a unit for identifying the signal reflected from said search object out of said differential signal.
