SkyRadar Long Range Radar for Civil Aviation

ADLER - the Long Range Radar

ADLER is SkyRadar's Long-Range Radar for Civil Aviation and  Perimeter Surveillance, covering long distances from 0 to > 5,000 m or 0 to 10,000 m. It operates with 77 GHz - and may require a specific operating permission in your country. The radar communicates with the home-based via (W)-LAN. Many applications for civil monitoring or surveillance purposes are available.

The system is equipped with a horn antenna. It is protected against dust and splashing water, perfectly suited for outdoor operation. 

The product will be installed outside, placed on a fixed-mounted rotary tripod. The system is not suited for mobile or military applications.

Signal Processing

  • Amplification
    • Amplification of raw signal (IQ signal) at receiver
    • Amplification of filtered signal possible
  • Filters and Signal Treatment
    The following filters and signal treatments are possible before interfacing the signal to a Intrusion Detection or Air Traffic Control system.
    • Sensitivity Time Control (STC)
    • Hamming
    • Hanning
    • Blackman
    • Blackmanharris
    • Signal Threshold and Limiter
    • Range Calibration and Extension
    • Cutting out selections of the signal range
    • Moving Target Detection and Indication
    • and more
  • Interface Formats
    • ASTERIX (latest format, as standarized by EuroControl)
    • JSON
  • Proprietary formats on request to interface with Intrusion Detection Systems and non-standard ATC systems
  • The advantages of Bare Die technologySmaller Size and Weight 
    • Using bare die can allow for reduced board space.Operating Temperature Size - Package thermal characteristics no longer inhibit the performance of the die or the environments where they can operate.

    • Ruggedness - Direct die attach and wirebond provides protections against high levels of shock and vibration.

    • Lighter Weight - Smaller designs and higher densities reduce weight and size of your application.

    • More Efficient Performance -  Removing extra package interconnect can reduce capacitance and inductance.

    • Reliability - The reduced number of interconnects with die use leads to improved reliability.
      The typical packaged part has three connection points per I/O. Compare this with only two for wire bonds.

    • Electrical Performance - The lower inductance and capacitance of bare die is important in analog, RF, and power applications.
      Faster signal flight time (lower propagation delay) and improved power/ground distributions.

    • Hermetically Sealing - Air tight sealed packages can be selected that can be injected with inert gasses.

  • Optional: ATC supervision screens for civil use (PPI, analytics).
