Abstract
In this paper some results are presented of a R&D project in progress which will be finished with a prototype of wide bandwidth subsurface radar (or, ground penetrating radar – GPR). This radar will be able to detect mines-like objects to allow classification of them. Subsurface radar technology is quite well understood already. In this project the main effort is focused on R&D to properly adopt methods and radar technology available worldwide in order to build a technologically advanced prototype. Expected scientific results of the project may reveal new details between image inversion/migration and the system physical layer (antennas, modulation, etc.). Object classification is still a scientific challenge with no doubt. There are no many methods available, but effectiveness of those existing is rather pure. In general, it is assumed in the project (in obvious way) that the better quality of the image the better classification can be done, with human perception or automatically (ATR). That is why the stepped frequency continuous wave (SFCW) radar is being built, working in wide frequency range (up to 18 GHz). Flexibility of this kind of radar allows to compromise the penetration depth with possible image resolution, according to the specific system task.
