Effective Strategies for Signature Analysis
Signature requirements for EO/IR seek to define how easily a vehicle, ship, aircraft, or spacecraft can be “acquired” or recognized as distinct from the background environment. It is similar to defining a maximum signal-to-noise ratio for a given platform: the lower the signal, the less distinct it is from the noisy background imagery. Because the requirements for signature often dictate the maximum contrast relative to the background, leading OEMs contract with ThermoAnalytics to plan ahead for effective strategies to minimize or control signatures, leading to improved performance and what is often termed, “low observables” design. Furthermore, as the global leaders in EO/IR simulation and engineering, ThermoAnalytics can help optimize multiple factors in the overall requirements for a platform, such as achieving a weight requirement while simultaneously reducing EO signature with a low observables kit.

Predicting Survival + Effectiveness
Predicting human thermal survival involves simulation across several distinct domains to be computed simultaneously – the environmental conditions over time, a detailed human physiology model that includes thermoregulation, and clothing models to capture both heat transfer and mass transfer resistance. Humans are thermally quite fragile and many critical biological processes are highly sensitive to temperature, including cognition. Thermal survival is limited to the study of how the body responds to dehydration, hypo- and hyperthermia, ignoring the situational effects of reduced cognitive capacity on the choices an individual makes when overheated or suffering from cold exposure.

Adversary signature prediction
EO/IR image outlier detection is a process that enables persistent observation systems a reliable way to flag image frames that might show the presence of a target or collection of features. Image outlier algorithms are considered an established but evolving technology that benefits from large volumes of EO/IR imagery produced under known, or, better yet, controlled conditions. ThermoAnalytics’ combination of software developers, modeling experts and scientists collaborate to produce virtual datasets for training such deep learning outlier classifiers.
