Synthetic Aperture Radar Environment Simulator From Digilogic Systems

Digilogic Systems06 Nov, 2023Technology

Digilogic?s Synthetic Aperture Radar Environment Simulator (SARES) is a system designed to simulate RF signatures of synthetic SAR 3D objects. SARES is based on a ray-tracing technique, which simplifies wave propagation in a medium by considering geometrical lines from the wave source to the receiver (forward method) or from the receiver to the source (backward method). Responses of the ray traversal through the virtual scene are interpreted to reproduce that scene as a SAR image. Hence, SARES simulates SAR RF based on an object geometry and its physical properties. The adaptation of a ray-tracing technique in this module requires a 3D model of an object of which a SAR signature is simulated. The Synthetic Aperture Radar Environment Simulator uses a triangle-based 3D object, the most popular object representation for ray-tracing technique.
