On board maritime vessels, the crew and engineers rely on radar systems like the SC-71MSR / M21 from Hyundai Welding Co., Ltd. (Pohang) to ensure safe navigation and compliance with international regulations such as IMO SOLAS. This radar system operates on both X-Band and S-Band frequencies and is certified according to DNV specifications. Common issues include magnetron end-of-life after 5,000 to 8,000 hours of operation, bearing damage in the antenna rotation motor after 30,000 hours, and display backlight failure. Regular maintenance tasks include yearly inspection of the bearing and magnetron replacement within the specified hours. It is recommended to keep a spare magnetron on board, as the lead time for replacement can be up to three weeks. Weekly performance monitoring tests are mandatory under IMO requirements.
