Sažetak
In the landmines detection for humanitarian demining, prodding is an important method, usually accompanied with the rather high false alarm rate. That makes the demining rather slow and dangerous. Prodder can be accompanied with the ultrasonic system, in case of which it serves as ultrasonic waveguide for ultrasonic impulses that are used for buried object materials characterisation. Based on the characterisation results, the buried objects are classified as rocks, wood, glass, metal, or plastic. The surface layer of the object is used in characterisation, hence its inner layers and structure does not influence the result. PRodder temperature is determined, and used in process because its changes influence the ultrasonic propagation. In that way, the reliability of a device does not depend on the seasonal, climatic, and other conditions that may induce the temperature changes and influence the ultrasonic impulse's propagation.
