SAR imagery of ocean-wave swell traveling in an arbitrary direction [PDF]

open access: yes, 1984
The intensity wave like patterns observed in Synthetic Aperture Radar (SAR) are known to be caused by two mechanisms: the microwave radar cross sectional amplitude modulation due to tilt and hydrodynamic interaction of the long ocean waves, and intensity

Bathymetry using Synthetic Aperture Radar (SAR) satellites

open access: yes, 2017
Maritime SAR applications: Synthetic Aperture Radar (SAR) is an active remote sensing technology. Radar satellites emit and receive their own signals and, hence, do not need to rely on sunlight for their acquisitions. Another benefit compared to optical satellites is SARs ability to look through clouds, which means data acquisition is very reliable ...

SEASAT views oceans and sea ice with synthetic aperture radar [PDF]

open access: yes
Fifty-one SEASAT synthetic aperture radar (SAR) images of the oceans and sea ice are presented. Surface and internal waves, the Gulf Stream system and its rings and eddies, the eastern North Pacific, coastal phenomena, bathymetric features, atmospheric ...

A multifrequency evaluation of active and passive microwave sensors for oil spill detection and assessment [PDF]

open access: yes
An evaluation is given of how active and passive microwave sensors can best be used in oil spill detection and assessment. Radar backscatter curves taken over oil spills are presented and their effect on synthetic aperture radar (SAR) imagery are ...

Necessity to adapt land use and land cover classification systems to readily accept radar data [PDF]

open access: yes
A hierarchial, four level, standardized system for classifying land use/land cover primarily from remote-sensor data (USGS system) is described. The USGS system was developed for nonmicrowave imaging sensors such as camera systems and line scanners.

Synthetic Aperture Radar (SAR) for Millimeter Wave Applications

open access: yes
Abstract If an application requires angular resolution capabilities, radar images or environment models that have a significantly better resolution than what is possible with MIMO radars or grid mapping approaches, the principle of the synthetic aperture radar (SAR) can be utilized.
