3D surface-penetrating radar "Defectoscope"

A surface-penetrating radar, called "Defectoscope", is described. It is intended to investigate various media and, in particular, to detect defects in building constructions. One of the characteristic features of the radar, designed on the basis of a portable computer, is the availability of an ultrasonic exact positioning system that allows automatic collection of radar data for three-dimensional imagery of the volume under the investigated surface. Results of sensing of a concrete wall with armature and placed behind it metal and plastic objects are presented. Results of experiments on the polarization recognition of subsurface objects are discussed
