Airborne optical sensors are widely used in remote sensing applications, acquiring information about remotely located objects on a flying aircraft in optical electro-magnetic spectral bands. These sensors passively gather electro- magnetic (EM) radiation reflected or radiated by the object of interest or surrounding areas. The sensors record spatial and/or spectral information which arises on an electro-optical detector(s). Here, we develop a MATLAB-based simulation code which precisely predicts the formation of images by the optical sensors while considering all optical aspects of light propagation in sequence from the object through the atmosphere to the detector. This code is used to assess the impact of various operational conditions on the final image quality in terms of a modulation transfer function, the Strehl ratio and the bore-sight error. Sample results are presented for an airborne payload following a brief explanation of the theoretical models used in the imaging path.
