Efficiency of the Algorithm for Previous Detection of the State of a Transmitting Laser Means Based on Reception and Analysis of Non-Stationary Pre-Generation Spontaneous Radiation

An algorithm for detecting a useful signal by an optical receiver, which is a non-stationary radiation increasing over a certain interval in Poisson noises of a stationary nature, is proposed. The efficiency of the algorithm is estimated taking into account the implementation of the process of weighted summation of the received input signal, which is an additive mixture of useful and noise radiation in the accumulation mode. Analytical expressions are obtained with an estimate of the main characteristics (average and dispersion), summed non-uniform weighted readings from the adder output and the distribution function of the pre-threshold effect for various hypotheses. For the case under consideration, the conditional probabilities of correct detection of a false alarm are estimated.
