Modern Technology

GMWR-400-SST Splashplate Antenna

GMWR-400-SST Splashplate Antenna

The GMWR-400-SST systems employs well proven designs and component of Doppler weather radar systems, including:

  • GAMIC reliable fully solid-state transmitter technology
  • Fully solid state modulator and power supplies
  • Integrated low noise receiver front end
  • ENIGMA IV – Digital signal processor-receiver
  • The GMWR-400-SST is the ONLY small transportable weather radar on the market, which provides DOPPLER wind velocity measurement function!

Better Performance

Low phase noise integrated receivers and the ultra-low phase noise STALO, developed by GAMIC, alloy the best possible sensitivity and coherence. Digital Doppler velocity measurement gives accurate velocity data over the entire range and optimal clutter cancelation.

Low Investment and Operating Cost

The stable, well proven design using standard ship radar components, adds up to a system with very low investment and small operating costs.

Available Options Protect Investment

Available options allow upgrading to meet future requirements, protecting today’s investment:

  • TV interface and graphics system provides broadcast quality radar and weather graphics images. Images can also be sent to Internet web server.
  • Hydrological analysis software provides full analysis product generation capability including volume scan products and hydro – meteorological rainfall analysis.
  • Specific 1.2 splash blade antenna design
  • Antenna and pedestal are typically mounted on
    • a stationary tower
    • a vehicle
    • on self-erecting hydraulic mast
