Compact Underground Radar System

Pulse radar systems, known as subsurface interface radars, have been widely used to locate underground objects. Three-dimensional towershaped antennas were developed to replace conventional plane antennas and accurately detect the location and depth of underground objects like gas pipes, water pipes and transmission cables. The newly developed radar system using these tower-shaped antennas is capable of locating not only metal but polyethylene pipes. Another important feature of the new radar system is that there is no need for the cable to connect high-frequency signal processors, including a CRT display. In addition to this, the use of lead storage batteries for power makes i t possible for a single person to operate the radar system. Since the new radar system has three frame memories of 512 k bytes and a IEEE standard 488-1978 terminal, image processing would be possible in the future.
