摘要
Abstract
With the characteristics like super-high resolution,three-dimensional imaging,and all-aspect angle observa-tion,circular synthetic aperture radar (CSAR) has become the hotspot in the field of SAR.In practice,almost all the ob-served targets are anisotropic targets thus it is not necessary to carry out the coherent processing within the whole aperture. Correspondingly,a Fourier-based sub-aperture imaging flow which has higher efficiency is proposed.The expression and a-nalysis of the spectrum of CSAR are presented,as well as the proposed Fourier-based imaging flow.Theoretical analysis and simulation test depict that both the proposed signal model and the imaging flow are available for CSAR.关键词
