Abstract: The U.S. Air Force, Navy, and Army are in the process of upgrading the Electro-Optical Tactical Decision Aid (EOTDA). The EOTDA has been used to predict the impact of weather and time of day on target acquisition. The upgraded program is called the Target Acquisition Weather Software (TAWS). New features of the TAWS will include: automated data access; upgraded path radiance routines; replacement of separate infrared (IR); television (TV) and night vision (NV) sensor performance models with Acquire; and a U.S. Army standard sensor performance model, which has become a standard in Department of Defense for IR, TV, and NV systems. To quantify the effects on predicted target acquisition range of upgrading the sensor performance model, a comparison of the TAWS Version 2 with Acquire has been undertaken. Weather effects on target acquisition are examined also in some detail.
