1.1. Overview This equipment is marine radar equipment satisfying the IMO standard. The radar equipment consists of a scanner unit that generates transmitting signals, transmits and receives radio waves, and amplifies receiving signals, and a display system that displays radar images after removing unwanted radio wave from the radar signals. The radar equipment with which a magnetron tube is used as the transmitting tube transmits 9.4 GHz (X band) pulse-modulated waves.
1.3. Display System The display system processes a radar signal transmitted from the scanner unit, removes unwanted radio wave, and plots/displays radar images in a specified observation range. The user is to stand in front of the display system and observe the conditions around the own ship with the radar images displayed on the display unit by operating the switches and trackball on the operation unit.
