Frequencies used are typically between 20 and 150 MHz depending on the application. New high power design achieves a transmitted power of 30 kilowatts. Not destructive or harmful to the environment in any way. The equipment is small and light weight and easy to use underground. Very useful in confined spaces, or in vertical mountings for viewing through a wall or hillside, or in other situations where a cart radar can not be used.
Radar can be monostatically or bistatically mounted.
Very good distance resolving power. Does not generate RFI or electrical interference. Battery powered if AC power not convenient. Not suitable in high clay or some types of moist soils where radio-frequency attenuation is extremely high. Low angular resolution typical of dipole antennas.
