Abstract

The modeling and analysis of infrared target and background signatures continues to be a topic of interest in the DoD. The question in many individuals minds is: What is the purpose of these signature prediction activities? After all, the sensor perfonnance modeling community tends toward the use of simplistic target and background representations in their models. Typically signature inputs to sensor models are nothing more than target delta temperatures which assume homogeneous targets and backgrounds. This paper attempts to answer the following two questions: 1 .Why do current sensor models have moderate to high fidelity modeling of the sensor subsystems and systems performance and low fidelity input target/background signatures? and 2. Is a high fidelity target and backgmund signature required to provide a meaningful estimate of sensor perfonnance? Examples of current sensor models and predictive target and background signature models are provided and discussed. A challenge is issued to the sensor modelers to learn more about signature prediction models and to be innovative in their use in development of future sensor perfonnance methodologies.
