This radar system operates on the principle of electromagnetic radar, utilizing X-Band and S-Band frequencies to comply with IMO SOLAS regulations. The SC-91K2 Cored / C1 model by Hyundai Welding Co., Ltd. (Pohang) is designed with reliability in mind, featuring DNV approval. Common issues include magnetron end-of-life after 5,000 to 8,000 operating hours, which requires a spare magnetron to be kept on board. Antenna rotation motor bearing damage can occur after 30,000 hours, and display backlight failure, heading marker misalignment, and waveguide moisture intrusion may also occur. Regular maintenance includes yearly antenna bearing lubrication and a weekly performance monitor test as per IMO requirements. Annual inspections are also recommended to ensure continuous compliance and operational readiness.
