Enhanced Degraded Visual Environment (DVE) Sensor

Share this page

Dual-band, dual-function radar sensor that combines both long distance X-band weather monitoring and high-resolution 

W-band Degraded Visual Environments (DVE) imaging of obstacles through brownout, whiteout and fog.

The Telephonics Advantage

    • Ideal upgrade path for existing Wx radar installations requiring DVE functionality
    • Combined sensor size is within 20% of a typical single function weather radar
    • Multi-mode DVE operation
      • Frequency Modulated Continuous Wave (FMCW) mode for close-in operation in the landing zone down to zero foot range
      • Pulse modulated mode for operation en route at distances of several miles
    • Shared X- and W-Band pedestal 

Additional Benefits

    • Optimized for low weight and high scanning rates
    • “Nodding beam” elevation control for obstacle height measurement
    • Scan pattern optimized to cover Field of Regard without wasting timeline on dead space
