20120191335 | TARGET IDENTIFICATION DEVICE AND TARGET MOVEMENT PREDICTION METHOD - A target identification device in a user object includes: a user information obtaining part and a target information obtaining part obtaining a position, a speed over ground and a course over ground of the user object and a target object; a processor that calculates a CPA distance and a TCPA with respect to the target object relative and the user object, based on the positions, the speeds over ground and the courses over ground of the user object and the target object. The processor replaces the course over ground of the user object with a direction toward the target object and calculates the CPA and the TCPA when the speed over ground of the user object is a low speed determination value or less. | 07-26-2012 |
