“…Figure 2 illustrates the electromagnetic scattering phenomenon of a simplified ship model. According to [1], the scattering from the ship mainly contains eight kinds of scattering. For weak computational burdens, not all of them are to be modelled and suitable approximations are adopted.…”

“…So it would effectively improve the researches on ship classification using SAR imagery. Though lots of researches have been done on the SAR imagery simulation of ship targets (e.g., Baussard et.al [1] studied simulated SAR system for maritime target imaging using a PO-based approach, Chen et.al [2] presented an efficient slope-deterministic facet model for SAR imagery simulation of marine scene, etc. ), it is still challenging.…”

Ship detection and classification with space-borne SAR has many potential applications within the maritime surveillance, fishery activity management, monitoring ship traffic, and military security. While ship detection techniques with SAR imagery are well established, ship classification is still an open issue. One of the main reasons may be ascribed to the difficulties on acquiring the required quantities of real data of vessels under different observation and environmental conditions with precise ground truth. Therefore, simulation of SAR images with high scenario flexibility and reasonable computation costs is compulsory for ship classification algorithms development. However, the simulation of SAR imagery of ship over sea surface is challenging. Though great efforts have been devoted to tackle this difficult problem, it is far from being conquered. This paper proposes a novel scheme for SAR imagery simulation of ship over sea surface. The simulation is implemented based on high frequency electromagnetic calculations methods of PO, MEC, PTD and GO. SAR imagery of sea clutter is modelled by the representative K-distribution clutter model. Then, the simulated SAR imagery of ship can be produced by inserting the simulated SAR imagery chips of ship into the SAR imagery of sea clutter. The proposed scheme has been validated with canonical and complex ship targets over a typical sea scene.
