Geometry Perturbations in High Fidelity Millimeter Wave Target Modeling for Scene Generator Systems

Radar target models are often developed from measured or predictive data sources that utilize a single instantiation of target geometry.Ā 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.Ā This signature variability can introduce significant effort in ælast mileÆ radar target model development and validation, often requiring iterative regeneration of target data.Ā For Phase II research, SSI builds upon feasibility demonstrations of Phase I efforts, to continue research, definition, and development of advanced radar scattering center objects that support direct correlation of target geometric perturbations to electromagnetic characterizations.ĀĀ These advanced radar model representations 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.Ā In addition to foundational research, Phase II efforts will also define requirements for programming interface and usage with select AvMC scene generation systems.
