Estimate of the overall angular dimensions of objects in case of detecting low-intensity radiation fields

It is shown, by simulating the estimates of counts of the correlation function (CF) of the scattered low-intensity laser radiation field, that the detection of intensity counts at different spatial points and the subsequent determination of the parameters of the CF of scattered radiation make it possible to estimate the angular size of objects being located with a high precision when the average number of photocounts detected within the observation interval does not exceed 0.1-1.0. In this case, a pulsed laser location system can provide the recognition of objects at ranges of a few thousands of kilometres. (pattern recognition)
