Abstract

A series of IR images from a mosaic sensor in geosynchronous orbit is simulated. This simulation includes the area around Santa Cruz, two layers of moving clouds, high and low level targets, simulated line of sight drift, and the composite optical-detector transfer function. Eight algorithms were tested on the simulation for target extraction and clutter rejection: four temporal differencing algorithms, temporal adaptive filtering, spatial adaptive filtering, spatial differencing, and a modified LMS filter. Background suppression factors up to 722 and target extraction of 25 dB. are reported for the simulation developed.
