A fundamental study of bistatic UWB radar for detection of buried objects

We have developed a bistatic radar system for detection of buried objects. The targets include buried land mines, and explosive material in a wall. The system is composed of a fixed transmitting antenna and a small receiving antenna. The receiving antenna uses a passive optical electric field sensor. Due to its small size of the receiving sensor, the operation of the system is easy in various conditions. Then we propose an effective signal processing by F-K filtering. By suppressing the strong transmitting signal, we could obtain clear images of the buried objects. We think this radar system is useful in various security issues.
