- W1979009075 abstract "Abstract Point targets (with size equal to the point spread function (PSF) of the detector system) in starfield, earth and cloud backgrounds are considered. We consider target detection from the background( using two frames of data and allowing the use of simpler sensor systems), target location estimatesof the target's position to subpixel accuracy (allowing the use of fewer sensor elements with bettersensitivity and cost), and track initiation (to confirm targets to be passed to a multi-target tracker).Real background sensor data and equivalently real targets are used and optical lab results are provided. 1 Introduction We consider the SDI (arid ADI) target acquisition issues of the detection and tracking of objects in midcourse when a strong background is present. We use simulated correlated noise data to model thebackground in a dowrtlooking scenario and a real starfield background (with various practical sensor errors) for the background in an uplooking scenario. In both cases, our algorithm can accomodatebackground shifts between frames (due to platform stability in an earth based or low orbit satellite" @default.
