METHOD AND APPARATUS FOR ESTIMATION THE NUMBER OF TARGET IN A SENSOR NETWORK ENVIRONMENT FOR SURVEILLANCE AND RECONNAISSANCE

摘要

PURPOSE: An apparatus for estimation the number of targets in a sensor network environment for surveillance and reconnaissance is provided to trace track through a detected target information. CONSTITUTION: An apparatus receives a location identification information of a target from a cluster head(S201). The apparatus classifies the identification information of the target(S203). The apparatus establishes an initial group value for the number estimation of the target(S205). The apparatus calculates the center point, and an inter-center point Euclidean distance(S207). If the Euclidean distance of two groups is smaller than the threshold value, the apparatus annexes two group values(S209,S211).
