Many of the technologies has been developed and tested across various test sites and in different Envoirment for detection of Landmines. This paper brings focus on available technologies for buried explosive detection with the help of number of available sensors. Various sensor technologies like Infrared sensors, ultrasound sensors, X-ray used to frame image subsurface at various depths. Technologies like Electrical Impedance Tomography (EIT) uses conductivity distribution underneath soil to make prediction about underlying metallic or non metallic objects. Explosives vapor detection (EVD) techniques make use of chemical composition of material for potential detection. In other way technologies like Ground penetration radar (GPR) uses very high frequency electromagnetic waves to image subsurface soils. Data gathered from precise sensors and then processed to find out anomalies by signal and image processing techniques such as feature extraction by texture mapping or by analyzing spatial conductivity distribution over the surface of interest. Processing techniques are developed in a way to enhance detection probability and to reduce false alarm rate.
