Detecting terrorists: Requirements and system specifications for a radar-based system

In this paper, the authors derive the specifications for a security system capable to detect so-called suspicious human activities using an affordable network of radar sensors. This work constitutes a first step towards the development of a robust day-and-night twenty-four hour surveillance system performing real-time automatic detection of terrorists in public places. Such device would complement the work of screening officers and assist decision-takers by providing information and time required to trigger preventive and protective actions. This paper is the result of a collaborative work undertaken by a team of academics with expertise in both the physical and social sciences at University College London.
