The purpose of the Smart Weapons Operability Enhancement (SWOE) Joint Test and Program is to validate the SWOE synthetic scene generation procedure. Once validated, this procedure will hopefully change the design-test-redesign approach to smart weapons development, test, and evaluation. Using the SWOE process, smart weapons designers will be able to evaluate their sensor algorithms on simulated scenes with a greater degree of variability than is often presented during the test phase of the design process. The SWOE process will also allow for the smart weapons design to be evaluated for different environments without the need for expensive and time-consuming data collection exercises. This report is an analysis of thermal data collected by the U.S. Army Engineer Waterways Experiment Station during the Yuma 1 field program exercise 15 March - 30 April 1993. The report aids in understanding variations in terrain features' infrared signatures using image metrics and presents the data in a format that could be used for synthetic scene validation tasks. The report also describes in graphical format the meteorological and terrain data at the time the infrared imagery data were collected., Original contains color plates: All DTIC reproductions will be in black and white

This report is an analysis of thermal data, collected by the U.S. Army Engineer Waterways Experiment Station during the Grayling II field program exercise 4 March-15 April 1994, that can be used to understand variations in terrain features' infrared signatures using image metrics and to present the data in a format that can be used for synthetic scene validation tasks. This report describes in graphical format the meteorological data at the time the infrared imagery data were collected.
