A subsurface radar using a multi-frequency signal has been developed. It is designated for surveying building structures and works. The characteristic feature of this device is the possibility of obtaining sounding plane radio images featuring a high resolution attaining 1…2 cm. The main applications of this device includes the survey of building structures to reveal their heterogeneities and defects and the investigation of premises to detect bugging devices  相似文献

We describe a new method of minefield reconnaissance with use of the broad size detector. The method allows terrain radio images to be obtained in the band of the mine detector sensors. The experimental installation was created with a set of radio ground probing sensors. To treat the radio images and to reduce the number of false alarms, spatial algorithms were proposed. A mine detector of this kind can be used in peacekeeping and humanitarian operations  相似文献
