An Approach for Determining the Location of an Object Detected by a Sensor

The objective of ensuring the security of industrial sites, especially those of major economic and social importance or of special production, is of paramount importance to any country. To this end, a number of organizational and technical measures are taken, in most cases involving the use of a variety of sensors to provide physical protection in the different control and security systems. At the following paper the focus is set on probabilistic nature of location of an alleged intruder. Therefore in the security systems of critical infrastructure a combination of various sensors is being used in order to attain higher probability of correct detection and to minimize the dispersion of the measured coordinates.
