Modeling and simulation of vessel in SAR image using oceanographic measured data and shipbuilding drawings

Abstract

Application of computational electromagnetic algorithms for simulating synthetic aperture radar (SAR) imagery of vessels has been researched for many years, but it is rare when a complete data set of oceanographic measurements and shipbuilding drawings is used and compared with the real‐time SAR image. In January 2016, an experiment to investigate SAR imaging of vessels was conducted in the East China Sea. Data acquired are used in this paper to test simulation algorithms of moving ship, dynamic ocean wave, and SAR imaging. Reasonable agreement is obtained when comparisons are made between the simulated and real SAR images.

“…Hammer et al [14] used a simulation imaging approach to investigate the SAR signature of oil tanks with fixed and floating roofs. Liu et al [15] suggested a method to simulate the SAR images of ship in different motion states by constructing the mesh model of the vessel, and the hydrodynamic models of the dynamic ship wake and ocean surface. Yoshida et al [16] explained the mechanism of azimuthal ocean wave emerged in SAR image spectra under specific condition based on a numerical simulation.…”
