Surface penetrating radar as an aid to search operations

The article presents the principle of operation of surface-penetrating radar for hidden object detection; this involves an impulse of a few microseconds' duration. Ancillary requirements are discussed. Surface penetrating radar relies for its effectiveness on efficient coupling of electromagnetic radiation into the ground, adequate penetration of the radiation through depth, obtaining from buried objects or other large dielectric discontinuities a sufficiently scattered signal for detection at or above the ground surface, and an adequate bandwidth in the detected signal having regard to the desired resolution and noise levels.
