Weather Radar

Long Range Quantitative Precipitation Estimation.

Supply, installation and maintenance of radars custom-built to your needs

ADASA designs, installs and maintains custom-purpose radar systems adapted to specific needs.

Weather radars gather an immense amount of information about the composition and distribution of atmospheric precipitation over an enormous range, up to hundreds of kilometres in radius. Radars detect, in real time, every litre of water content between the ground and a layer 15km above the earth’s surface. They also provide information about the water’s physical state: hail, snow, or liquid.

Radars can measure wind speed distribution within its range - air traffic controllers can be advised of adverse gust fronts and wind shear conditions near runways.

Radar applications are many, aside from meteorology; civil protection agencies, air traffic safety, irrigation decisions, mitigation of damage in case of floods, cloud seeding for rain and more. Our data storage solution allows real-time events to be followed, as well as the study of historical precipitation events.

Every radar subsystem and its relevant circuit is permanently monitored via an implemented Built In Test Equipment (BITE). Each radar subsystem generates a warning or an alarm in case of detecting any malfunction.

Additionally, we have developed an application (WRADS) to check all radar’s images meet strict quality rules. Both systems generate an email notification to our technicians when any anomaly is detected.

ADASA offers a complete radar package, from equipment supply to civil works for site conditioning, from installation and commissioning to maintenance.

Our radars can provide different types of data:

  • Instant real-time scan image.
  • 360° image of the echoes received: T
  • Doppler moments: V, W, Z.
  • Dual Polarization Moments: LDR, ZDR, RHOHV, PHIDP, KDP.
  • Derivative products: PPI, RHI, CAPPI, MAX, VCUT and more.

Colour codes show the intensity of rainfall, giving an immediate and intuitive representation of the amount of precipitation across the map. Two-dimensional maps offer various layers of information that can be activated. Some products provide three-dimensional maps that convey the intensity and distribution of precipitation within a weather event.

An animation of N images, generally the most recently generated, gives a visual, intuitive representation of how the precipitation is evolving.

We offer C-Band, S-Band or X-Band for long-range and high or low sensitivity.

TECHNOLOGY

X-Band (9.4 GHz):

  • Small size
  • Low cost
  • High sensitivity
  • Low cloud penetration during heavy rain episodes
  • Short-range (60-120km)
  • Suitable for managing hydrological basins

C-Band (5.6 GHz):

  • Medium size
  • Mid cost
  • Mid sensitivity
  • Mid cloud penetration during heavy rain episodes
  • Mid-range (120-240km)
  • Very good for general radar meteorology

S-Band (2.8 GHz):

  • Bigger size
  • Higher cost
  • Lower sensitivity
  • High cloud penetration during heavy rain episodes
  • Long-range (240-400km)
  • Suitable for cyclone-prone areas
