Integrating deep learning-based data driven and model-based approaches for inverse synthetic aperture radar target recognition

Optical Engineering: The Journal of SPIE, 2020
. We explore the blending of model-based and deep learning approaches for target recognition in inverse synthetic aperture radar (ISAR) imagery. It evaluates five different approaches, namely, a model-based geometric hashing approach, a supervised deep ...

An eigenvector approach for inverse synthetic aperture radar (ISAR) motion compensation and imaging

TENCON '97 Brisbane - Australia. Proceedings of IEEE TENCON '97. IEEE Region 10 Annual Conference. Speech and Image Technologies for Computing and Telecommunications (Cat. No.97CH36162), 2002
Inverse synthetic aperture radar (ISAR) is a high resolution imaging radar. The image reconstruction of ISAR involves two steps; motion compensation and image formation. In this paper, an eigenvector approach is proposed to carry out ISAR motion compensation.

Micro‐Doppler effect removal for inverse synthetic aperture radar imaging based on augmented Lagrange multipliers

Microwave and optical technology letters (Print), 2020
Micro‐Doppler (MD) effect may decrease the readability of inverse synthetic aperture radar (ISAR) imaging results, so it is more desirable to solve the problem of MD effect removal.

Inverse Synthetic Aperture Radar Imaging Using Fourier Transform Technique

2019 1st International Conference on Innovations in Information and Communication Technology (ICIICT), 2019
Inverse Synthetic Aperture Radar (ISAR) imaging techniques are used to estimate the target spatial image using target backscatter data. In the ISAR measurement environment, the target is often modeled as a collection of point scatterers to take advantage

Resolution enhancement for inverse synthetic aperture radar images using a deep residual network

Microwave and optical technology letters (Print), 2019
A framework for inverse synthetic aperture radar (ISAR) image resolution enhancement using a deep residual network is proposed. Our framework directly learns an end‐to‐end mapping in the form of a deep residual network (ResNet) between the input low ...
