Inverse Synthetic Aperture Radar Simulator Implementation for an Extended Naval Target for Electronic Warfare Applications

Airborne Inverse Synthetic Aperture Radar systems provide excellent surveillance abilities for imaging naval targets. Considering this as a maritime surveillance threat we derive a simulator system in this paper that can be used to synthesize false targets that would appear as credible military fleets. The resulting electromagnetic signature synthesis allows the implementation of returns that appear to backscatter from areas of high reflectivity as arranged in military superstructures instead of commercial counterparts. The conceptual model for this simulation is constructed by considering standard representation theory. The modelling approach follows standard abstraction degrees for the three-dimensional synthetic environment, target fidelity and inverse scattering. The pace engine that acts as the computing moving force for the simulation is mathematically presented. The inverse scattering signal follows standard ISAR theoretical guidelines. The data exchange standard between the various elements is presented. Issues in implementation and project success are discussed by drawing upon the verification and validation analyses.
