PROBLEM TO BE SOLVED: To provide an integrated analysis system for information of two or more sensors capable of maintaining detection operation of a target, corresponding to various conditions of the target, when the motion of the target changes rapidly or the like. SOLUTION: The integrated analysis system is composed of two or more acoustic sensors, an observation section, a multiplex trajectory evaluation section, a trajectory correlation section, and an integrated analysis section. In the observation section, observation signals of the acoustic sensors are analyzed, and an observation signal value at each position in an observation region of each sensor is computed. In the multiplex trajectory evaluation section, a trajectory of a target is detected from observation information by observation performed by time series with each acoustic sensor using two or more different evaluation indexes, or two or more evaluation indexes obtained by setting different parameters with respect to one evaluation index. In the trajectory correlation section, identity of two or more trajectories detected by the individual acoustic sensors is determined using each distance between the trajectories. In the integrated analysis section, trajectories determined to be identical are integrated, and existence of the target is determined. COPYRIGHT: (C)2005,JPO&NCIPI
