what is sar
WhatIs SAR?
  • SAR = Synthetic Aperture Radar
  • Onboard a Polar-Orbiting Satellite
  • SAR is an active sensor that transmits microwave radiation in pulses and records the radiation backscattered in the direction of the sensor.
  • Measures the return energy off the wavelets caused by the local wind
  • Algorithm converts the data into an estimated wind speed
basic strengths deficiencies of sar
Basic Strengths & Deficiencies of SAR
  • Strengths:
  • High resolution
  • Can see through clouds & at night
  • Deficiencies:
  • Needs prior knowledge of wind direction
  • Not available in real time
