Vehicle Control System

The platform of scatterometer is designed to be light-weight and easy to operate. The elevating platform uses hydraulic pressure lift system with movable design. Users can easily access observation height, incident angle, and multi-angle / multi-polarization configurations from the built-in System Controller.

  • Observation height - up to 20 meters
  • Incident angle - 0 - 180° ( continuous )
  • Precision of incident angle – up to 0.2°
  • Transition period between different incident angles-less than 30 seconds
  • Changeable polarization during observation
  • Transition period between different polarization channels-less than 1 minute
  • Controller with GPIB and Ethernet interface for connection
  • Data processing and storage
