Attitude Estimation for Space Targets by Exploiting the Quadratic Phase Coefficients of Inverse Synthetic Aperture Radar Imagery

IEEE Transactions on Geoscience and Remote Sensing, 2019
This paper proposes a novel approach to interpreting the satellite attitude based on inverse synthetic aperture radar (ISAR) images. In the conventional viewpoint, quadratic and higher order phase terms of ISAR imagery are regarded as negative factors ...

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 ...

Demonstration of Ultra-high-resolution Photonics-based Kaband Inverse Synthetic Aperture Radar Imaging

Optical Fiber Communications Conference and Exhibition, 2018
We demonstrate a photonics-based Ka-band radar system with 12 GHz bandwidth by optical signal generation and de-chirp processing. Inverse synthetic aperture radar imaging with a range resolution as high as ∼1.3 cm high-resolution is achieved.

Inverse synthetic aperture radar imaging exploiting dictionary learning

International Radar Conference, 2018
We consider the Inverse synthetic aperture radar (ISAR) imaging with under-sampled data in the framework of compressive sensing (CS) theory. In the existing studies of CS based ISAR imaging or sparse ISAR imaging, the scene to be imaged is simply assumed

Pattern-Coupled Sparse Bayesian Learning for Inverse Synthetic Aperture Radar Imaging

IEEE Signal Processing Letters, 2015
We propose a pattern-coupled sparse Bayesian learning method for inverse synthetic aperture radar (ISAR) imaging by exploiting a block-sparse structure inherent in ISAR target images.
