SFCW GPR sensor with phase processing for landmine detection and recognition

The phase isoclines close to the plexiglass box location moves down. So it is the criterion of dielectric object presence. The phase isoclines close to the metallic object location moves up. So it is the criterion of metallic object presence. Also we can make conclusion that using both the SAR and phase structure images allows detecting and recognition objects similar a landmine. But in the hard soil conditions the detection probability will be not very high.
