Abstract:

The influence of out-of-field laser interference on the detection characteristics of an infrared optoelecronic system for surveillance of quasi-point objects is considered. Analytic expressions based on the description of the probability density function of the noise signal, using an approximation in Gaussian form, are proposed for estimation of the probabilities of false alarm and missing a quasi-point surveillance object (target). The average value (mathematical expectation) of the detected noise signal and the parameter M that characterizes the statistical properties of scattered laser radiation incident on the focal matrix are the parameters that determine the specific form of this function. The aforementioned parameters are determined while processing experimental frames obtained under the out-of-field laser exposure of the model optoelecronic system.
