Abstract

From December 2009 thru 2011 the NASA Wide-Field Infrared Survey Explorer (WISE) gathered radiometrically exquisite measurements of debris in near Earth orbits, adding substantially to the current catalog of known debris. Assuming grey-body emissivity, the apparent size of debris objects may be inferred from that data. This report describes a general model for debris size distributed near the GEO belt. Linear and nonlinear regression models were fit to data from the WISE orbital debris catalog. Using those results we estimate the sensitivity of the instrument to detection of small debris objects near the GEO belt.
