The assumption of weak scattering is standard for the mathematical analysis of synthetic aperture radar (SAR), as it helps linearize the inverse problem via the first Born approximation and thus makes it amenable to solution. Yet it is not consistent with another common assumption, that the interrogating waves do not penetrate into the target material and get scattered off its surface only, which essentially means that the scattering is strong. In the paper, we revisit the foundations of the…

Through-the-Wall Nonlinear SAR Imaging
Numerical comparison with the solution of the linearized inverse scattering problem provided by the Born approximation, commonly used in conventional SAR imaging, shows a significantly better accuracy of the results.
Imaging Simulation for Synthetic Aperture Radar: A Full-Wave Approach
The full-wave method is applied to include the electromagnetic effects in raw data generation, and then a refined omega-K algorithm is used to perform image focusing, and the results compare well with chamber experiments.
Detection of delayed target response in SAR
A simple model of a delayed scatterer is developed by modifying the random function that describes a homogeneous extended scatterers to obtain a relation between the deterministic parameters of the target model and statistical moments of the SAR image.
A mathematical perspective on radar interferometry
Radar interferometry is an advanced remote sensing technology that utilizes complex phases of two or more radar images of the same target taken at slightly different imaging conditions and/or
Fourier Analysis, Computing, and Image Formation for Spotlight Synthetic Aperture Radar
This article revisits imaging of random complex signals from frequency data as in SAR, providing simpler derivations of some previous results and extending these ideas to the continuous setting and regularization methods are presented to improve the quality of SAR images.
Modeling radar targets beyond the first Born approximation
In this chapter, we return to the foundations of the SAR ambiguity theory that we presented in Chapter 2, and address the inconsistencies of the conventional approach outlined in Section 2.7 A
Quasi-Born approximation scattering and inverse scattering of multiple scattering targets
Conditions in which forward scattering of multiple scattering point-like targets behaves like Born approximation scattering are derived in the framework of the Foldy-Lax multiple scattering model.
Conventional SAR imaging
This chapter explains the fundamental principles of SAR data collection and image formation, i.e., inversion of the received data, which can be categorized as a coherent imaging technology.
Joint Down-Range and Cross-Range RFI Suppression in Ultra-Wideband SAR
The experimental results demonstrate that the 2-D model does a much better job of capturing the sparsity of SAR and the 2 -D algorithms consistently perform better than the “local” 1-D algorithms.
Polarimetric radar interferometry in the presence of differential Faraday rotation
Faraday rotation (FR) affects the low-frequency transionospheric radar by creating cross-talk between polarizations. The baseline part of FR can be compensated for by applying an appropriate linear

For the image to stay largely unaffected by Doppler, the frequency shift must be included in the definition of a matched filter, otherwise, there will be a geometric shift (translation) of the entire imaged scene from its true position, and there may also be a slight deterioration of the image sharpness (contrast).
Dual Carrier Probing for Spaceborne SAR Imaging
This work concludes that the deterioration of SAR images was due to the mismatch between certain parameters of the actual received signal, which is slowed down by the temporal dispersion in the ionosphere, and the corresponding parameter of the matched filter, which was taken as if the propagation were unobstructed.

This paper reviews basic synthetic aperture radar (SAR) theory of ocean wave imaging mechanisms, using both known work and recent experimental and theoretical results from the Marine Remote Sensing
On SAR Imaging through the Earth's Ionosphere
The ionospheric phenomena, both deterministic and random, are shown to affect the azimuthal resolution of a SAR sensor stronger than the range resolution; also, the effect of randomness appears weaker than that of the baseline dispersion.
Reduction of ionospheric distortions for spaceborne synthetic aperture radar with the help of image registration
We propose a robust technique for reducing the ionospheric distortions in spaceborne synthetic aperture radar (SAR) images. It is based on probing the terrain on two distinct carrier frequencies.

An approach to autofocusing for large curved synthetic aperture radar (SAR) apertures is presented. Its essential feature is that phase corrections are being extracted not directly from SAR images,

We discuss the single-polarization SAR imaging with the Faraday rotation (FR) taken into account. The FR leads to a reduction in the intensity of the received radar signal that varies over the signal
