Abstract

Qualitative comparisons of electro-optical (EO) sensor field performance measurements and model predictions are presented for a variety of nonideal weather situations including fog, haze, rain, high absolute humidities, and high temperatures observed at Wright-Patterson AFB, Dayton, Ohio. Commercially available 3-5pm and 8-l2pm AGA Thermovision imagers and an RCA silicon charged coupled device (CCD) TV camera are being used at the Air Force Avionics Laboratory (AFAL) Targeting Systems Characterization Facility (TSCF) to observe natural and man-made targets. The imagery are analyzed digitally to determine how much weather degrades EO sensor performance. Initial comparisons of field sensor perfor mance measurements and model predictions indicate that the AFAL Sensor Performance Model (ALSPM) correctly predicts sensor performance degradation trends due to nonideal weather. Future field sensor measurements and validation efforts will attempt to quantify ALSPM prediction accuracy and isolate critical input data.
