The problem of detection of a signal from stars and meteors with the use of an IR matrix detector to estimate their parameters and the parameters of the atmosphere is discussed. It is shown that the uncertain position of the spot of an object image on the receiving matrix leads to the essentially different statistical characteristics of the signal. The mathematical expectation and variance of the signal are calculated both with and without regard for the signal absorption in the gaps between the sensitive elements. The obtained results are used to explain some experimental data.
