PROBLEM TO BE SOLVED: To provide a system and a method for correlating a measuring area data, in a passive coherent search system. SOLUTION: A detection report is correlated with a target signal received, in passive coherent search system. A measured value of the detection report is correlated with data of the target signal. A line track state estimation function part correlates a new detection report with a line track, and estimates an updated state of the line track. A signal type is determined. A Kalman filter is selected as to be measured value in response to a signal type. Error in the measured value of the detection report is calculated, in response to the Kalman filter. The detection report is selected as being correlated with the line tracks in response to the error. The line track can be composed or finished during an updating period, according to a prescribed reference. Furthermore, a new line track is initialized, when a new target is detected.
