Simulation Study of the Dynamic Sea Influence on SAR Imaging of Ships

Abstract

The ship with sea background SAR imaging simulation technology has a great significance for the detection and identification of the ship with sea background target and the design and verification of the SAR system. In order to improve the fidelity of the ship with sea background SAR simulation image, this paper constructing a dynamic sea surface model, combined with the ship's three-dimensional model and electromagnetic scattering model, the signal-level SAR imaging simulation of the sea-ship composite scene is carried out, and the SAR simulation image with high fidelity is obtained, and compared with the simulated images in the static sea scene, it intuitively reflects the realistic degree of SAR simulation images in dynamic sea scenes and can provide help for ship target detection and recognition in sea clutter background.
