Bistatic GPR system for landmine detection using optical electric field

Ground penetrating radar (GPR) is one promising technique for land mine detection, and many researches have been carried out. Most of the ideas for landmine detection by GPR use a monostatic type radar system, which is suitable for detecting land mines buried in shallow soil, which is normally less than 10 cm. On the other hand, bistatic type radar will be suitable for stand-off detection. In this paper, we propose a novel bistatic radar system, which uses an optical electric field sensor as a receiver. Some fundamental field test results are shown in this report.
