Title:
METHOD AND SYSTEM FOR DIRECTING FOLLOW-UP APPARATUS TO MOVABLE TARGET
Document Type and Number:
Japanese Patent JP3493337
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method and a system for directing a movable target to a follow-up device, without complicating or increasing the constitution of a follow-up target and that of the follow-up device.
SOLUTION: An automatic target follow-up system 10 has a tracking part 12, related to a follow-up device 34 and a leading part 14 related to a follow-up target. The tracking part 12 has a 1st processor 15 and at least two converters 16a, 16b for generating an encoded ultrasonic signal. Each converter has a control input part connected to the 1st processor 15, in order to generate the encoded ultrasonic signal to the leading part 15, in response to a command signal from the 1st processor 15. The encoded ultrasonic signal stores originating source identification information. A radio-frequency(RF) receiver 18 is connected to the 1st processor 15, in order to receive an encoded RF signal storing the distance and direction information of the leading part 14 from the tracking part 12, which is used for the purpose of steering the follow-up device to the direction of the follow-up target from the leading part 14.
