摘要
To obtain a signal tracking device with which it is possible to correctly track a plurality of intersecting signals in a noise-present environment.SOLUTION: The signal tracking device comprises: a track calculation processing unit for determining a combination of two or more intersecting tracks and finding a track having highest detection prior probability out of the combination; an assignment processing unit for assigning a likelihood function to the track found when the number of peaks of the likelihood function is one when two or more signals intersect; a calculation processing unit for calculating a tracking prior probability density function, with the effect of diffusion removed in accordance with a convection equation, at a time when no likelihood functions are assigned to a temporarily extinct track to which the likelihood function has not been assigned; a retention processing unit for retaining a target class for a temporarily extinct track until the intersection of two or more signals is resolved; and a fixation processing unit for fixing the target class of the temporarily extinct track to the target class retained by the retention processing unit when the detection probability of the temporarily extinct track occurs successively before and after the intersection of two or more signals.SELECTED DRAWING: Figure 1
