Tohoku University has developed dual sensor ALIS for humanitarian demining and 2 sets of ALIS are used by CAMC (Cambodian Mine Action Centre) since 2009 and detected more than 80 mines. We have demonstrated the performance of mine clearance using ALIS together with CMAC. In 2017, we launched a new advanced ALIS as a commercial product. Based on the development and field evaluation since 2002, the advanced ALIS, which weights 3100g, is a compact device, which can visualize the GPR and Metal Detector response on a display of a PAD attached to the sensor. The system can acquire the sensor position information and metal detector signal together with GPR signal. Then, we process the GPR signal and reconstruct subsurface image to detect buried mines. We found that the reconstruction algorithm is the key technology to determine buried mines under very strong clutter condition. We conducted evaluation test of ALIS in a test site in Cambodia, and could show ALIS can visualize the buried mine very clearly. We are planning to deploy ALIS in mine affected countries including Cambodia and Colombia.
