Ground-probing radar, also known as subsurface radar, is becoming an important subject. The number of applications for ground-probing radar is growing and the technology is beginning to be employed in other radar fields; for example, impulsive or carrier free radar, which is in widespread use for ground probing, is now being developed by the military for its anti-Stealth capabilities. Ground-probing radar is one of the few ways of inspecting geological features and locating hidden objects and structural flaws. The technique is not new, but it is only since the advent of fast digital processing and microprocessors that sufficient low-cost signal and data processing has been available to solve many of the problems raised by this type of radar.
