Subsurface penetrating radars

Subsurface penetrating radars (SPR) are designed for subsurface monitoring and are able to execute detection, location determination and diagnosis of subsurface areas and objects at a new quality standard level. Basic problems regarding the design of such radars are examined in this paper. They are: the choice of frequency band for radio probing and the type of probing signal, information acquisition strategy, aperture generating method, estimation of resolution, dynamic range and capabilities of the system; algorithm design for radar imaging with respect to specific character of super wide band probing signal; system components design, including antenna, transmitting and receiving modules, information processing and screening module.
