S-316.16N

The electromagnetic radar works by emitting radio waves that bounce off objects and return to the receiver, providing distance measurements. The S-316.16N model from Hyundai Welding Co., Ltd. (Pohang) operates on X-Band and S-Band frequencies, ensuring compliance with IMO SOLAS requirements. Common failures include magnetron end-of-life after 5,000 to 8,000 hours of operation, bearing wear in the antenna rotation motor, display backlight failure, heading marker drift, and water intrusion into the waveguide due to pressure issues. To mitigate these risks, it is advised to keep a spare magnetron on board (on models with a magnetron) and replace it every 5,000 to 8,000 hours. Additionally, lubricate the antenna bearing annually, conduct weekly performance monitor tests as per IMO standards, and perform an annual inspection.
