<p>PROBLEM TO BE SOLVED: To provide a ship radar device which can display radar images in a stern-up display mode with direction of a stern set right up on a radar screen when a ship sails sternward. SOLUTION: When a display mode switch 8 outputs a signal indicating a stern-up display mode, a CPU 3 outputs an offset value representing a rotating angle of a radar image necessary to display the radar image on a radar screen of a display device 2 in the stern-up display mode, and stores the value as a set value in an offset memory part 21. A display control part 22 displays the radar image rotated by the rotating angle represented by the set value on the radar screen of the display device 2 in the stern-up display mode.</p> |
