A Hand-Held Dual-Sensor System Using Impulse GPR for Demining

摘要

A hand-held dual-sensor system for demining has been developed. The system integrates ground-penetrating radar (GPR) and a metal detector. One of the features of the system is imaging capability. The system achieves the position information by tracking the sensor head. Thus synthetic aperture radar (SAR) processing can be applied and the performance can be significantly improved. The system was tested by real deminers in Croatia 2007. The trial results confirmed that false alarms (alarms from other than landmines) were significantly reduced by using GPR, meaning total demining operation can be accelerated. Them we started a half-year evaluation test of the system in quality-control (QC) test in Croatia in December 2007. This test will be conducted in various soil environmental conditions in Croatia.
