Baron VHDD-300X Radar

300 kW X-Band Magnetron System

Applications:

• Designed to deliver exceptional accuracy for research applications and short-range meteorological surveillance

• Available in mobile and fixed configurations

Features and Benefits

Powered by a 300 kW X-band magnetron

Proven magnetron performance in any weather situation.

Dual-polarization as standard option

Simultaneous horizontal and vertical transmission results in more precision analysis for flooding, hail, winter precipitation and tornadoes.

Next-generation radar processor

The onboard Baron signal processor delivers value-added product creation and automated storm tracking. Full command and control enables on-the-fly RHI and sector scans at the meteorologist’s discretion.

Superior clutter suppression

Available exclusively from Baron though a license of technology with the University of Oklahoma, CLEAN-AP™ enables superior ground clutter suppression, in addition to optimally and dynamically adapting the suppression process to the ground clutter environment.

Radial-by-radial ZDR calibration

This new patent-pending technology provides reliable and continuous network-wide calibration during any weather conditions, with less maintenance and on-site expertise required.

Open data architecture

All Baron VHDD radars feature an open architecture for easier access to data at various points throughout the processing chain.

Reliable and easy to maintain

Wide-access panels provide easy access to major components, reducing man hours on preventive maintenance and repair. Pedestal motors deliver rugged durability, and can be easily replaced without removing the elevation head.

Spare parts can be shared across multiple systems in the field, which reduces costs and maximizes uptime.

Remote system monitoring and 24/7 support

Built-in test equipment provides automatic notification to personnel if potential issues occur. Additionally, meteorologists from the Baron operations center are available to address questions and troubleshooting around the clock.
