In this paper we describe a new method of minefield reconnaissance with use
of the broad size detector. The method allows getting the terrain's radio
images to be obtained in the band of the mine detector sensors. The experim
ental installation was created with set of radio ground probing sensors. To
treat the radio images and to reduce the number of false alarms the spatia
l algorithms were proposed. A mine detector of this kind can be used in pea
cekeeping and humanitarian operations.
