  • JPL is developing L-band SAR, while ISRO is developing S-band SAR.

  • L & S band microwave data obtained from this satellite will be useful for variety of application.

Applications of NISAR Sensor

  • Natural resources mapping & monitoring

  • Estimating agricultural biomass over full duration of crop cycle

  • Assessing soil moisture

  • Monitoring of floods and oil slicks- Glacial Lake Outburst Floods (GLOF) hazards and identifying inundated area due to floods/cyclones

  • Monitoring coastal erosion, coastline changes, variation of winds in coastal waters

  • Assessment of mangroves

  • Surface deformation studies

  • Study of ice sheet collapses & dynamics- identifying crevasses in the glaciers hidden by fresh snow, where human movement takes place and identifying the snowpack parameters as an input in Avalanche forecasts

Details of Synthetic Aperture Radar (NISAR)

  • The L band is the designation for the range of frequencies in the radio spectrum from 1 to 2 gigahertz with applications in mobile service, satellite navigation, aircraft surveillance, broadcasting, and astronomy.

  • The S band is part of the microwave band of the electromagnetic spectrum covering frequencies from 2 to 4 gigahertz.

  • The S band is used by weather radar, surface ship radar, and some communications satellites to communicate with the Space Shuttle and the International Space Station.
