We describe the architecture and design of a through-the-wall radar. The radar is applied for the detection and localization of people hidden behind obstacles. It implements a new adaptive processing technique for people detection, which is introduced in this article. This processing technique is based on exponential averaging with adopted weighting coefficients. Through-the-wall detection and localization of a moving person is demonstrated by a measurement example. The localization relies on the time-of-flight approach.
The IST-2000-25348-BIOSENS project carried out a number of studies to assess the use of explosive detection technology for humanitarian demining. This paper presents sampling/collection technology developed, test methodology and results including comparisons with dogs and soil sampling. Findings are presented in terms of the detection of explosive from mines in the environment and demining.

This paper presents the development results for three sensor technologies: metal detector (MD) array, ultrawideband (UWB) ground penetrating radar (GPR) array and biosensor sample collection and analysis system. It provides results on explosives findings for demining and demonstrates how the false alarm rate (FAR) of the MD may be reduced while maintaining high probability of detection (PD) through a data fusion (DF) system. The relevance of the results to demining and homeland security is also provided.
