ONWA Açık Dizi Deniz Radar Anteni
Unparalleled Performance
Superior Detection Capabilities
Each model in the ONWA Open Array Radar series delivers superior detection capabilities, allowing you to accurately identify and track targets at various ranges. Whether navigating congested waterways or open seas, these radars provide the clarity and detail needed to make informed decisions.
High Resolution
X-Band radar offers higher resolution compared to other frequency bands, allowing for detailed imagery and precise detection of small objects or vessels. This makes it particularly useful in navigation where accuracy is crucial.
Target Tracking
The radar system can simultaneously track multiple targets, providing detailed information on their position, speed, and direction. This feature is essential for avoiding collisions and maintaining a safe navigation path.
The KM Series allows radar data to be overlaid on nautical charts, combining visual navigation aids with real-time radar information. This feature enhances situational awareness by showing radar echoes on the chart, making it easier to correlate radar returns with charted objects.
