Target Oriented High Resolution SAR Image Formation via Semantic Information Guided Regularizations

open access: yes, 2017
Sparsity-regularized synthetic aperture radar (SAR) imaging framework has shown its remarkable performance to generate a feature enhanced high resolution image, in which a sparsity-inducing regularizer is involved by exploiting the sparsity priors of ...

Fourier Analysis, Computing, and Image Formation for Spotlight Synthetic Aperture Radar [PDF]

open access: yesarXiv, 2019
This article is written to serve as an introduction and survey of imaging with synthetic aperture radar (SAR). The reader will benefit from having some familiarity with harmonic analysis, electromagnetic radiation, and inverse problems. After an overview of the SAR problem and some main concepts, the SAR imaging problem is contextualized in terms of ...

2-D Coherence Factor for Sidelobe and Ghost Suppressions in Radar Imaging [PDF]

open access: yes, 1956
The coherence factor (CF) is defined as the ratio of coherent power to incoherent power received by the radar aperture. The incoherent power is computed by the multi-antenna receiver based on only the spatial variable.

Performance limits for maritime Inverse Synthetic Aperture Radar (ISAR) [PDF]

open access: yes, 2013
The performance of an Inverse Synthetic Aperture Radar (ISAR) system depends on a variety of factors, many which are interdependent in some manner. In this report we specifically examine ISAR as applied to maritime targets (e.g. ships). It is often difficult to get your arms around' the problem of ascertaining achievable performance limits, and yet ...
