TL;DR: Simulation results demonstrate that the proposed implementation of the IAA based on the Doppler-convolution model and Dopplers centroid estimation can overcome the deficiencies of the SAR and DBS techniques in the forward-looking imaging direction, and present a noticeably superior performance as compared with conventional AFLR imaging methods.

TL;DR: The underlying idea is to equalize the space-variant Doppler centroid embedded in an inversion operator for a reference range cell using Dopplers centroid compensation, which can significantly reduce the necessary computational complexity for 2-D AHSR inverse-scattering reconstruction.

TL;DR: A fast IAA (FIAA)-based super-resolution DBS imaging method, taking advantage of the rich matrix structures of the classical narrow-band filtering, using the Hermitian feature of the echo autocorrelation matrix R to achieve its fast solution and uses the Toeplitz structure of R to realize its fast inversion.

TL;DR: A novel data-depended Doppler centroid estimation method that can significantly provide reliable estimation accuracy under low echo signal to noise ratio, independent of conditions that strictly required by conventional methods is proposed.

TL;DR: In this paper, a Doppler beam sharpening (DBS) imaging method was proposed to achieve the high azimuth resolution in the forward-squint region based on fast iterative adaptive approach (F-IAA).
