Seasat was the first NASA satellite with synthetic aperture radar deployed. It operated on L-band in 1978 for 105 days until its catastrophic power failure.
Before and After Images showing the difference between the Seasat images being optically processed shortly after the mission and digitally processed in 2013
The Alaska Satellite Facility was tasked by NASA with creating a digital archive of focused synthetic aperture radar (SAR) products from data collected by NASA’s Seasat mission. The basic steps involved in this process are as follows: Capture the raw signal data from tape onto disk Validate and byte-align the raw signal data Decode the …
This section provides a detailed description of the HDF5 data format used for the final generation of Seasat synthetic aperture radar (SAR) products. Although it does not cover a technical challenge, it is included for completeness of the processing description.
Sea-ice imagery and data products are supported under NASA’s Making Earth System data records for Use in Research Environments (MEaSUREs) program.
RADARSAT-1, which stopped transmitting because of a technical anomaly in March 2013, was equipped with synthetic aperture radar (SAR), a powerful microwave instrument. It transmitted and received signals for capturing high quality images of the Earth night and day and in all-weather conditions. RADARSAT-1’s SAR transmitted a microwave energy pulse (C-band at 5.3 GHz frequency) …
UAVSAR collects L-band synthetic aperture radar data over various sites. Coverage maps, technical specifications, and how to cite information are available.
Sentinel-1 Data Coverage Heat Maps Data are open-access and available through Vertex. Click on an image below to see where data products are available. Cumulative Acquisition Maps Two Cumulative Heat maps are updated monthly as new data are processed. One map displays the total coverage of Sentinel-1 Ground Range Detected (GRD) product data over the globe …
