Applied Physics and Mathematics Annotation << Back PASSIVE DETECTION PROBABILITY AT DELIBERATE INTERFERENCES A.A. MOISEEV Basing on passive detection model developed methods for locks influence analysis on detection probability. In particular were found dependences of signal -to- noise ratio and corresponding probabilities from jammers number. As lock threshold were used protection coefficients dependent on noise -to- signal ratios. Thereupon were estimated locks influence on locator detection and detection probabilities at different false alarm levels. Keywords: passive detection, active locator, deliberate interferences, jammer, lock threshold, signal -to- noise ratio, detection probability, protection coefficient, false alarm level.
