Abstract

The paper presents the concept of a multisensor system for perimeter protection, suitable for stationary and moving objects. The system consists of an active ground radar and thermal and visible cameras. The radar allows the system to locate potential intruders and controls an observation area for system cameras. The multi-sensor system concept ensures significant improvement of the probability of intruder detection and reduction of false alarms, thus increasing the functionality and performance of the whole system. Effective ranges of detection depend on the quality of the applied sensors and the observed scene itself. One of the most important devices used in such systems are IR cameras. The paper discusses the technical possibilities and limitations to use uncooled IR cameras in such a multi-sensor system for perimeter protection. The role of IR cameras in the system was discussed as well as a technical possibilities to detect a human being. The operational distances for perimeter protection are rather high, considering the performance of commercially available thermal cameras. The required spatial resolutions for detection, recognition and identification were calculated and then the detection ranges were estimated using NVTherm software. The results of analysis were finally presented and the comparison of exemplary IR cameras.
