Optimum Threshold Detection for an Infrared Nutating Detection System

摘要

A threshold detection system based on the Neyman-Pearson criterion is derived for an infrared nutating optical system. Detection is optimum for small signal-to-noise ratios and a Gaussian uncertainty in the pointing error of the optical system. The signal spectrum and background power spectral density for a rectangular space filter are computed numerically and used to specify the matched filter for the threshold detection system and evaluate its performance.
