TARGET TRACKING DEVICE ERRONEOUS ALARM ANALYSIS METHOD, ANALYZER AND ANALYSIS PROGRAM

摘要

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 sets as parameters a transition probability of each state, a state probability in the number of observations a and the number of detection object cells on the basis of processing content of the target tracking device, generates a state transition matrix on the basis of the transition probability of each state, calculates a state probability of each state in the number of observations b on the basis of the state transition matrix and the state probability of each state in the number of observations b, classifies the state from the state probability of each state in the number of observations b, totals the state probabilities of the states classified and calculates the number of tracks by multiplying the state probabilities classified and totaled by the number of the detection object cells. Each element of the state transition matrix is calculated by approximation processing in which the transition probability of each state and the difference between the number of observations c(=b-a) are set as parameters.
