Fast Matrix Inversion and Determinant Computation for Polarimetric Synthetic Aperture Radar [PDF]
This paper introduces a fast algorithm for simultaneous inversion and determinant computation of small sized matrices in the context of fully Polarimetric Synthetic Aperture Radar (PolSAR) image processing and analysis. The proposed fast algorithm is based on the computation of the adjoint matrix and the symmetry of the input matrix.

Low cost passive radar through software defined radio [PDF]
Passive radars utilise existing terrestrial radio signals, such as those produced by radio or television stations, to track objects within their range. This project aims to determine the suitability of low cost USB TV tuners as hardware receivers for a ...

Artificial light at night (ALAN) has global impacts on animals, yet its effects in polar regions remain underexplored. In this study, we analyzed a decade of citizen science data on seabird occurrences in Longyearbyen, using remote sensing data to assess the impact of ALAN during the polar night.

Radar Fields: An Extension of Radiance Fields to SAR [PDF]
Radiance fields have been a major breakthrough in the field of inverse rendering, novel view synthesis and 3D modeling of complex scenes from multi-view image collections. Since their introduction, it was shown that they could be extended to other modalities such as LiDAR, radio frequencies, X-ray or ultrasound. In this paper, we show that, despite the

Three Dimensional Inverse Synthetic Aperture Radar Imaging [PDF]
This research investigates the generation, display, and interpretation of three-dimensional (3-D) Synthetic Aperture Radar images. Three-dimensional assumes that the data collected consists of one temporal dimension and two orthogonal angular dimensions.

An improved inverse synthetic aperture radar range alignment method based on maximum contrast
Inverse synthetic aperture radar (ISAR) is an important tool for non-cooperative ship imaging, and one key step of ISAR imaging is range alignment. To achieve the range alignment with high precision, efficiency and robustness, an improved ISAR range ...

Graph Based Imaging for Synthetic Aperture Radar [PDF]
In this paper, we propose graph signal processing based imaging for synthetic aperture radar. We present a modified version of fused least absolute shrinkage and selection operator to cater for graph structure of the radar image. We solve the cost function via alternating direction method of multipliers.
