Inverse Synthetic Aperture Radar (ISAR) Imaging in the Presence of Electronic Attack (EA)

Helios Remote Sensing Systems proposes to develop and demonstrate a maritime Inverse Synthetic Aperture Radar (ISAR) imaging algorithm that is robust to electronic attack (EA). We will develop an innovative maritime ISAR imaging algorithm that is robust to EA for operation in highly contested environments. We will develop a novel ISAR framework and imaging algorithm that leverages the physics of radar backscattering theory of targets to greatly reduce the amount of data and acquisition time required to precisely reconstruct the ISAR images as compared to the traditional ISAR imaging approach. We will develop a toolkit approach with variable EA inputs to assess the robustness of the ISAR image algorithm and to assess the algorithm performance in terms of image quality against EA using simulated radar data of maritime targets. Our Phase I effort will include prototype plans to be developed under Phases II. During Phase II, we will assess the Phase I algorithm performance in terms of image quality and automatic target recognition against electronic attack using simulated and experimental radar data of maritime targets. We will complete the EA toolkit as a product that is compatible with the application radars to assess the ISAR image formation robustness and quality.
