Application Of Selective Linear Predictive Coding (SLPC) In Enhancing Cross-Range Resolution Of Inverse Synthetic Aperture Radar (ISAR)

SPIE Proceedings, 1989
High range resolution X-band Inverse Synthetic Aperture Radar (ISAR) using stepped frequency waveforms is described. Target images are produced by performing inverse Fourier transform in range dimension and linear predictive coding in the cross-range dimension.

An Efficient Basis for Decomposition of Cavity Returns in Inverse Synthetic Aperture Radar (ISAR) Measurements Using Basis Pursuit

2019 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2019
We recently described a technique called basis pursuit dictionary editing (BDPE) that uses L1 minimization techniques to remove contamination from ISAR measurements and imagery of rotating targets [1]. While our original BPDE technique works well when the target scattering is dominated by literal (non-interacting) returns, non-literal target scattering,

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 ...

Data Collection Eclipsing Effects in the Inverse Polar Format Algorithm (IPFA) for Turntable Spotlight Inverse Synthetic Aperture Radar (ISAR) Imaging Systems

2007 IEEE Radar Conference, 2007
This paper will present the findings associated with data eclipsing effects in the inverse polar format algorithm (IPFA) for turntable spotlight inverse synthetic aperture radar (ISAR) imaging systems. Typical turntable ISAR systems illuminate a scene of interest with an electromagnetic source in order to obtain samples of the reflectivity function ...
