The subsurface targets i.e. low metallic content mines or non-metallic landmines are one of the difficult subsurface targets to be detected using geophysical techniques. Ground penetrating radar (GPR) is one of the techniques used for the detection of these targets which has become popular due to its advantages like high resolution, non-contact sensing and being sensitive to changes in all types of electrical characteristics.As there is risk of loss of life the technology should support detection without digging in this application as well as the technique should be real time. The paper reviews the real time techniques for the landmine detection.
