APQ-102 imaging radar digital image quality study [PDF]

open access: yes
A modified APQ-102 sidelooking radar collected synthetic aperture radar (SAR) data which was digitized and recorded on wideband magnetic tape. These tapes were then ground processed into computer compatible tapes (CCT's).

OFDM Synthetic Aperture Radar Imaging with Sufficient Cyclic Prefix [PDF]

open access: yes, 2014
The existing linear frequency modulated (LFM) (or step frequency) and random noise synthetic aperture radar (SAR) systems may correspond to the frequency hopping (FH) and direct sequence (DS) spread spectrum systems in the past second and third ...

SWOT Water Surface Elevation in Herbaceous Wetlands of Florida's Everglades

open access: yesGeophysical Research Letters, Volume 52, Issue 9, 16 May 2025.
Abstract Observing water level variations in wetlands is important for tracking global water and carbon cycles. The Surface Water and Ocean Topography (SWOT) mission was launched to measure Earth's surface waters, but its performance in vegetated wetlands was unknown.

EXPERIENCE OF RADAR DATA PROCESSING FOR GEOGRAPHIC MAPPING

open access: yesInterCarto. InterGIS, 2014
New synthetic aperture radar (SAR) systems suggest new potentials for the environmental studies and mapping due to high spatial resolution, various beam modes and the full polarization mode. Current level of imaging radar development together with amount

A Multiple Radar Approach for Automatic Target Recognition of Aircraft using Inverse Synthetic Aperture Radar [PDF]

open access: yesarXiv, 2017
Along with the improvement of radar technologies, Automatic Target Recognition (ATR) using Synthetic Aperture Radar (SAR) and Inverse SAR (ISAR) has come to be an active research area. SAR/ISAR are radar techniques to generate a two-dimensional high-resolution image of a target. Unlike other similar experiments using Convolutional Neural Networks (CNN)

The Geometry of Spaceborne Synthetic Aperture Radar [PDF]

open access: yesarXiv, 2018
The paper defines a new coordinate system that was developed in 1977-78 for the world's first digital synthetic aperture radar (SAR) ground processor for images from the Seasat-A satellite. The coordinate system is for the range-Doppler paradigm in the context of a spaceborne platform orbiting a rotating planet.

Digital correlation of DDRS data [PDF]

open access: yes
The reduction of digital SAR (synthetic aperture radar) data to radar images for use in remote sensing applications was investigated. The critical software operations are discussed in detail, and suggestions and recommendations are made for improving the
