Prototype Automatic Target Screener

摘要

This report covers hardware modifications we have made since the last report, the modification to include range target/clutter discrimination, and the general status of the PATS system. The program objective is to produce a design for an automatic target screener. The screener will reduce the task loading on the thermal imager operator by detecting and recognizing a limited set of high-priority targets at ranges comparable to or greater than those for an unassisted observer. A second objective is to provide enhancement of the video presentation to the operator. The image enhancement includes: (1) automatic gain/brightness control to relieve the operator of the necessity of continually adjusting the display gain and brightness controls and (2) DC restoration to eliminate artifacts resulting from AC coupling of the infrared (IR) detectors.
