Improvised explosive devices (IED) are a major problem in military operations. Not least charges with homemade explosives (HME). The goal of this project is to give the Swedish Armed Forces an improved capability to detect and locate IED's and their components. In this report we briefly describe the activities in the project Sensors for detection of IEDs during 2013. The project, which runs 2013-2015 and is a continuation of a previous three-year project, includes a work package dealing with sensor fusion and the benefit of combining multiple sensors. We have demonstrated the ability to detect disturbed soil (digging tracks) with different techniques, based on the difference in emissivity at various wavelengths, anomaly detection in hyperspectral images or change detection. Initially the IED threat scenarios were was also updated. Laboratory tests with detection of disturbed soil have been done. In addition, further development of methods for hyperspectral anomaly detection was made. A previously conducted field trial of 3D lidar for change detection has been analyzed. In radar detection, work has mainly taken the form of keeping up with developments in the fields of ground-penetrating radar (GPR) and synthetic aperture radar (SAR) with application to the detection of buried objects. In Raman spectroscopy the work has focused on implementing Kerr gating as a method to suppress fluorescence, thereby improving the signal-to-noise ratio for the Raman signal from an explosive substance. In sensor fusion a flexible system architecture is designed, where information from different sensor combinations can be fused at different levels to improve the detection capability and reduce the number of false alarms. Work on sensor fusion has included an initial analysis. Sensor fusion experiments with previously collected data from EO sensors have demonstrated the ability to detect disturbed soil. At the end some results from international collaboration in working groups within EDA and NATO are described. Future work will mainly focus on further development of a thermal simulation model for buried objects, further experiments with detection of disturbed soil, and studies of various radar methods.
