Abstract
A method for characterizing anthropogenic space objects, includes the steps of: receiving, by computing device, sensing and imaging electro-optical pixel data respecting the anthropogenic space objects, performing, by the computing device, ambient level correction of the electro-optical pixel data by subtracting background noise attributed to wide field luminescence due to stars and cosmic radiation and creating, by the computing device, fast kinematic constructs for the anthropogenic space objects whereby the anthropogenic space objects are detected, discriminated and characterized.
Claims18
A method for characterizing anthropogenic space objects, comprising:
- receiving, by computing device, sensing and imaging electro-optical pixel data respecting the anthropogenic space objects;
- performing, by the computing device, ambient level correction of the electro-optical pixel data by subtracting background noise attributed to wide field luminescence due to stars and cosmic radiation;
- performing, by the computing device, Autonomous Ambient Level Correction (AALC) to provide deterministic processing within a limited interval and with reduced bandwidth required for results data transfer;
- completing, by the computing device, the AALC by (a) measuring a spatial gradient on both X and Y axes for each pixel in a current frame and a smooth filtered mean divergence sum, (b) updating during current frame processing weighted products and index weight sums, (c) computing current frame weighted centroid and updated filtered centroid and (d) computing an adaptive threshold to partially qualify pixels for hypothesis track coordinates in addition to a Gaussian divergence discriminant determined from the smooth filtered mean divergence sum plus two standard deviations;
- and
- creating, by the computing device, fast kinematic constructs for the anthropogenic space objects whereby the anthropogenic space objects are detected, discriminated and characterized.
