A new bistatic GPR system using a passive optical sensor for landmine detection

A novel GPR system for stand off landmine detection is discussed. This is a bistatic GPR system, which use a TEM horn antenna for a transmitter and a passive optical electrical field sensor as a receiver. A small size passive optical sensor scans on the ground surface and the acquired signal is used for synthetic aperture processing. Since the receiver is very small, it is suitable for scanning near the ground surface, where landmines can be buried. Fundamental laboratory test shows its capability of imaging of buried objects.
