EVALUATING METHOD FOR MARINE VESSEL COLLISION DANGER DEGREE

摘要

PURPOSE:To exactly operate and steer a marine vessel by bringing a degree of danger of an obstruction which has been caught by a centimeter wave radar, to an operation processing by an automatic collision prevention support device, and tracking precisely an obstruction which has been decided to have a danger of collision by its result, by a millimeter wave radar. CONSTITUTION:Other marine vessel being in a short distance is scanned at a high speed by a millimeter wave radar antenna 40, also tracked precisely, and the exact data of other marine vessel are updated at a high speed and inputted to a computer 60. By this computer 60, the own marine vessel is set as a surface of an occupied area, and a forecasting danger range of several ranks corresponding to a relative vector is set centering around the own marine vessel. Also, the data of other marine vessel which has been caught by a centimeter wave radar antenna 10 are brought to an operation processing by an automatic collision prevention support device 30, and as a result, only a target which has been decided to be dangerous is added to the computer 60. Next, only the target which has been decided to be dangerous is tracked precisely by the millimeter wave antenna 40, a degree of danger of its target is displayed on a display 70, and by its display, a good operating method is found out.
