PROBLEM TO BE SOLVED: To perform analysis processing for an erroneous alarm in a short time without using an actual target tracking device and a simulator thereof.SOLUTION: An erroneous alarm analyzer for performing analysis of an erroneous alarm issued by a target tracking device includes: a parameter setting part 5 for setting as parameters a transition probability of each state, a state probability in the number of observations a (a is an integer of 0 or more) and the number of detection object cells on the basis of processing content of the target tracking device; a state transition matrix generation part 1 for generating a state transition matrix on the basis of the transition probability of each state; a state probability calculation part 2 for calculating a state probability of each state in the number of observations b (b is an integer of 0 or more) on the basis of the state transition matrix and the state probability of each state in the number of observations a; a state probability classification/totaling part 3 for classifying the state from the state probability of each state in the number of observations b and totaling the state probabilities of the states classified; and a track number calculation part 4 for calculating the number of tracks by multiplying the state probabilities classified and totaled by the number of the detection object cells. |
