Title:
TRACKING EQUIPMENT OF MOVING TARGET
Document Type and Number:
Japanese Patent JP3154217
Kind Code:
B2
Abstract:
PURPOSE: To obtain a tracking equipment of moving target which can execute accurate tracking preestimation without depending on a simple average.
CONSTITUTION: When a position calculating means 5 determines a measured position XD(n) on the basis of a plurality of observed positions Xi(n) obtained by using a sensor part 1 and a tracking part 3 determines a smoothed position XP(n) on the basis of the measured position XD(n) and a preestimated position XS(n) determined at the preceding time, a preestimated position shifting means 29 of a preestimated position correcting part 25 shifts the smoothed position XP(n) into an error range for guaranteeing a positional probability (p) set beforehand, which is determined by an error range calculating means 23 of an error range setting part 20, when the smoothed position XP(n) is not within this error range.
