Weather Radar Systems

Vaisala single and dual polarization weather radars are designed to produce superior data quality and availability, meeting even the most demanding requirements. With industry-leading data processing and hardware design, they are perfect for a wide variety of applications.

Weather Radar System Diagram


Vaisala dual polarization weather radars are the standard for modern radar systems, producing clear, clutter-free, high-resolution measurements of rainfall events. They provide precise quantitative precipitation estimation (QPE) to help meteorologists gather rainfall accumulation measurements. They also include HydroClass, the world’s first automatic hydrometeor classification software for dual polarization radars. This helps to clearly distinguish between different types of precipitation and improve data quality by eliminating moving, non-meteorological targets.

Unrivalled Data Processing Performance

Vaisala weather radars are flexible and easy to use, with the most comprehensive and robust software in the industry – perfect for fast processing and sophisticated clutter filtering. 

Optimized Antenna Performance

The radar antenna plays a vital role in the quality of the data gathered. The dish shape, structure, and size optimize dual-polarization performance and provide excellent side-lobe reduction.

Simplified Maintenance and Operation

Vaisala systems can be accessed from anywhere via a secure network link, minimizing the number of site visits, while the integrated Uninterruptible Power Supply (UPS) ensures continuous operation during temporary power outages.
