Description

Radar target models are often developed from measured or predictive data sources that utilize a single instantiation of target geometry.  However real-world perturbations in target features can result in variability of dominant scattering features that subsequently produce significant variation in high fidelity scattering centers as well as composite target radar signatures.  This signature variability can introduce significant effort in ‘last mile’ radar target model development and validation, often requiring iterative regeneration of target data.  For Phase I research, SSI proposes the research, definition, and development of advanced radar scattering center representations that support direct correlation of target geometric perturbations to capture the effect of CAD structure variability, increase radar model signature fidelity, reduce overall target development time, and simplify validation complexity for both radar and CAD model end-products.  Requirements for AvMC scene generation systems, measurement and predictive data sources, frequency diversity, and CAD model inputs are addressed and defined.
