“…The results agree well with the measurements in Voronovich and Zavorotny . To calculate the ship scattering, a combination of PO with other CEM modeling techniques is adopted, including the physical theory of diffraction (PTD), and the parametric model of corner reflectors. The results of bistatic scattering have been verified by typical scatterers, such as flat plate, frustum, corner reflectors, and composite ship‐sea model .…”

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.

“…Some geometrical models are simply utilized to describe those scattering contributions [34]- [36]. For example, a plane, a cylinder, and a sphere may represent the scattering from a plane, single curvature, and double curved surfaces, respectively; a dihedral may describe double scattering, and a trihedral may present triple scattering; a dipole may represent edge diffraction [31]. In this paper, we select five kinds of typical geometrical models: 1) trihedral (plane or sphere); 2) cylinder; 3) dipole; 4) narrow diplane; 5) dihedral, which are commonly used to represent typical scattering types of man-made target, to characterize target scattering center types.…”

Geometrical Structure Classification of Target HRRP Scattering Centers Based on Dual Polarimetric $H/\alpha$ Features

Polarimetric high resolution range profile (HRRP) contains the geometrical structural information along radar line-of-sight and has shown great potentials in target recognition. In existing researches, H /α decomposition has been applied to exploit global polarimetric features of a single HRRP from its spatially averaged coherent matrix, which loses target local scattering information. In this paper, we propose to apply the H /α decomposition along the slow time dimension in a dual polarimetric HRRP sequence. The H and α features are extracted for each target scattering center by averaging its samples in different observations of the HRRP sequence, which provides both target local high resolution and polarimetric scattering characteristics. We also design a novel six-zone H -α plane for geometrical structure classification of target scattering centers. Simulation and experimental results show the effectiveness of the proposed method and display its good potentials for practical applications.
