The mi ssion will map Earth’s surface every 12 days\, on ascending and descendi ng portions of the orbit\, over all land and ice-covered surfaces. The mis sion’s primary objectives will be to study Earth land and ice deformatio n\, and ecosystems\, and support applications that benefit from systematic observations such as infrastructure monitoring\, agriculture\, soil moist ure\, and disaster response. The NISAR observatory carries two radars\, on e at L-band (24 cm wavelength) and the other at S-band (10 cm wavelength)\ , each with a swath of over 240 km at fine resolution\, using multiple pol arizations depending on the observation target. To achieve these unprecede nted capabilities\, both radars use a reflector-feed system\, whereby the feed aperture elements are individually sampled to allow a scan-on-receive (“SweepSAR”) capability at both L-band and S-band. The L-band and S-b and electronics and feed apertures\, provided by NASA and ISRO respectivel y\, share a common 12-m diameter deployable reflector/boom system\, provid ed by NASA. These two radars can operate simultaneously and both have on-b oard digital beamforming and filtering to reduce data rates. Nonetheless\, they produce prodigious amounts of data\, generating over 40 Terabits of data per day. Given the high data rates and ambitious coverage requirement s\, new technologies for high-rate Ka-band downlink complement these first -of-a-kind radar systems. The challenges of developing a complex multi-rad ar satellite jointly on opposite sides of Earth are great\, and the global pandemic of 2020-2021 has certainly increased those challenges. This talk will present the technologies and techniques of NISAR\, and describe the mission development process and progress.\n\nCo-sponsored by: Geoscience a nd Remote Sensing Society\n\nSpeaker(s): Dr. Paul Rosen\, \n\nVirtual: htt ps://events.vtools.ieee.org/m/283288 LOCATION:Virtual: https://events.vtools.ieee.org/m/283288 ORGANIZER:lep@umich.edu SEQUENCE:11 SUMMARY:The NASA-ISRO Synthetic Aperture Radar (NISAR) Mission – Technolo gies and Techniques for Earth Science URL;VALUE=URI:https://events.vtools.ieee.org/m/283288 X-ALT-DESC:Description: <br /><p>Webinar registration link: &nbsp\;<a href= "https://us02web.zoom.us/meeting/register/tZYrfuispzssH9UASjZHePI0Dg_rSTmW jTPv">https://us02web.zoom.us/meeting/register/tZYrfuispzssH9UASjZHePI0Dg_ rSTmWjTPv</a></p>\n<p>ABSTRACT:</p>\n<p>The National Aeronautics and Space Administration (NASA) in the United States and the Indian Space Research Organisation (ISRO) are developing the NASA-ISRO Synthetic Aperture Radar (NISAR) mission\, now planned for launch in 2023.
