<p>PURPOSE:To display wake information of the own ship and other ship, and navigation information such as a course, speed, etc., and a radar video, etc. on the same CRT, by basing on a technique of a wake display device and a radar, and utilizing a chart information for track-processing of a radar echo. CONSTITUTION:An own ship wake processing part 1 converts position information sent from a navigation device and sends it as chart information and wake informtion to a wake display part 2. Information sent from a radar is received by a radar interface 6, and a target tracking part 8 compares radar echo information with tracking unnecessary information from a control part 5, decides it, eliminates a land echo, extracts position information of other ship, and sends it to a display part 10 through an other ship route processing part 9. A mixer 3 synthesizes a video signal of a wake of the own ship and chart information, etc. from the wake display part 2 and a video signal of a radar video and a wake of other ship, navigation information, etc. from the display part 10, sends it to an indicator 4, and the indicator 4 displays the chart information, classified routes of the own ship and other ship, the navigation information and the radar video, on a CRT.</p> |
