Testing radar performance on a vessel involves several steps to ensure its functionality and accuracy. First, the radar system undergoes a visual inspection to check for physical damage and proper installation. Next, operational testing is performed by powering the radar and verifying that it can detect known targets at various ranges. Calibration procedures are performed to ensure the radar range and bearing measurements are accurate. Additionally, the radar performance is evaluated under different environmental conditions, such as different maritime states and weather conditions, to ensure reliability. The system is also tested for its ability to differentiate between targets and clutter and its responsiveness to operator controls.
Radar performance standards required by the International Maritime Organization (IMO) are outlined in the International Convention for the Safety of Life at Sea (SOLAS). These standards specify the minimum performance criteria that marine radar systems must meet to ensure safe navigation. Key requirements include a minimum detection range of 0.25 nautical miles for small targets, effective operation in a variety of sea and weather conditions, and the ability to clearly display targets with adequate resolution and accuracy. The radar must also provide reliable performance in detecting and tracking multiple targets and have features such as automatic tracking, collision avoidance and integration with other navigation systems like AIS (National Identification System automatic) and ECDIS (Electronic Chart Display and Information System). Regular testing and maintenance is necessary to ensure compliance with these standards.
