Method of substantiation of the algorithm of detection of multispectral spontaneous radiation and assessment of its efficiency

Based on the use of methods of the theory of optimal reception of optical signals, an algorithm of operation of a multichannel receiver operating in the photoelectron counting mode (transition formation) is proposed, as applied to the detection of pre-generation multispectral spontaneous radiation of the transmitting laser channel. Using the procedure of functional transformation of random values of counts in the studied algorithm, conditional probabilities of correct detection and false alarm are obtained, characterizing the operation of a multichannel receiver when detecting multispectral pre-generation spontaneous radiation.
