Abstract
Security equipment is of prime importance in the information protection systems at the secure facilities. These primarily include passive infrared detectors. However, when designing security systems, the problems with calculation of the coverage areas may emerge. This is due to the lack of theoretical research into the association of statistical detection with selection of parameters for the calculation of the maximum detection range. To solve this problem, a special technique was developed for application of the basic passive location equation for the calculation of coverage areas of infrared detectors.
The research was based on the equation of maximum range of passive receiver. Three cases of signal parameters and noise have been considered: signal detection through the white noise with fully known parameters, detection of signal the phase and amplitude of which are unknown, and detection of random signal through the noise.
The calculations allowed identifying the conditions that upon their fulfillment will lead to the correct use of the formulas for passive signal detection through the noise.
Conducted research allows associating the statistical detection theory with the equation of range of the passive radiator.
