ELECTRONIC WORM'S EYEVIEW

The article briefly describes a portable radar cable of detecting buried pipes, conduits, sewers and water lines whether encased in metal or plastic. The device is capable of "looking down" through concrete and several feet of soil and has been developed by Calspan Corporation, Buffalo, New York. The equipment can also be used for monitoring subsurface conditions of highways, detecting buried objects and even human or animal bodies buried in soil. It measures their size and depth below the surface within a few inches. The radar system weighs less than 20 pounds (9 kilgrammes) and has a horizontal boom of 10 feet with the antenna horn mounted vertically on the front. Batteries and transmitter are situated at the back of the boom. The equipment can be set to produce a video signal visible on the screen of a small oscilloscope on the operators chest or an audio signal in his headphones. The antenna is a constant-flare-angle variable--width open horn.
