GNSS-Based Passive Inverse SAR Imaging
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 The utilization of global navigation satellite system (GNSS) signals for remote sensing has been a hot topic recently. In this article, the feasibility of the GNSS-based passive inverse synthetic aperture radar (P-ISAR) is analyzed. GNSS-based P-ISAR can

Polarimetric ISAR autofocusing
IET Signal Processing, 2008 Interest in polarimetric inverse synthetic aperture radar (ISAR) systems has been growing because of their capability to provide extra information about the imaged target compared with single polarisation ISAR systems. Target classification and recognition can be improved by exploiting full polarisation ISAR images.

A New Denoising System for SONAR Images
EURASIP Journal on Image and Video Processing, 2009 The SONAR images are perturbed by speckle noise. The use of speckle reduction filters is necessary to optimize the image exploitation procedures.

Axial Attitude Estimation of Spacecraft in Orbit Based on ISAR Image Sequence
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 Attitude estimation is a significant task for monitoring noncooperative spacecraft in orbit. Inverse synthetic aperture radar (ISAR) is an effective method to obtain the structure, size, and attitude of spacecraft.

State transitions as morphisms for complete lattices [PDF]
, 1999 We enlarge the hom-sets of categories of complete lattices by introducing `state transitions' as generalized morphisms. The obtained category will then be compared with a functorial quantaloidal enrichment and a contextual quantaloidal enrichment that ...

Operational resolutions and state transitions in a categorical setting [PDF]
, 1999 We define a category with as objects operational resolutions and with as morphisms - not necessarily deterministic - state transitions. We study connections with closure spaces and join-complete lattices and sketch physical applications related to ...
