Dynamic Near-Field Radar Target Modeling in Scene Generator Systems

High fidelity scene generators utilize radar target models over the entire flight profile of a weapon system or sensor under test. As such, radar signatures generated from these models must encompass the entire simulation flight path to include a continuum of engagement conditions ranging from the far-field to very near-field. Signature Solutions, Inc. proposes a technical approach for dynamic and continuous sampling, correction, and implementation of near-field effects at the phase history level of target models and resultant I&Q signature data. The proposed approach and solution is applicable to existing and new signature data collections and target model developments and provides a generic implementation for scene generator applications. Current research provides feasibility analysis of the proposed technical approach as well as requirements definition and planning for scene generator implementation, viable metric evaluations, and validation requirements.
