This report provides a summary description of the work in the project Sensors for the detection of IEDs. The report aims to collect experience and to briefly describe and summarize results obtained during the project period of three years. The aim of the project was to study techniques to improve the ability to remotely detect and locate IED's and IED components. Various sensor technologies to achieve area coverage, high detection rate and real-time ability have been studied, in particular sensors with the ability to detect and classify hidden (eg. buried) objects. It has been shown in the project that it is not possible to cover the entire area of detection of IED with a single sensor. It is therefore necessary to study the interaction of several sensors, which leads to the need for sensor fusion. A sensor with high detection capability is used to cue other sensors - possibly with worse area coverage rate - which means that they can be cued to specific areas or points where used to confirm or reject detection. In future projects, specific methods of collaborative sensors for the detection of IEDs should be studied, as a modular architecture for flexible combinations of sensors in various threat scenarios. In the long term, with sensors for detecting electronics should also be integrated. Anomaly detection and change detection with suitable sensors should be studied further. Valuable insight into current research in other countries has been obtained through collaboration with international research groups. Project members have participated in the EDA "Expert Group on detection of IEDs" and in several working groups within NATO's research organization STO. Collaboration with other research institutes, for example within the framework of the trilateral collaboration agreement with Canada and the Netherlands, should be strengthened.
