Complex Target Imaging Model Based on Statistical Characterization and Structured Characterizations

The synthetic aperture radar (SAR) image of a complex target can be approximated by the composite composition of typical scatter bodies, by segmenting the SAR target image, the complex target can be decomposed into a structural combination of multiple scatterers. Based on the above conclusions, this paper proposes to model the structural components of complex targets under high-resolution observation conditions and construct a complex target imaging model, decompose a large complex ship target into multiple scattering bodies, coupled structures and large distribution areas, enhance the structured feature of complex targets based on the a priori knowledge of the coupling characteristics and distribution characteristics of known scatterers, and achieve the modeling of complex targets. this paper proposes a SAR imaging model with a combination of structural and statistical features to provide a new technical way of utilizing the data effectively.
