PROBLEM TO BE SOLVED: To provide an oceanic-sound tomographic-data analytical method where a tidal phenomenon is removed from observation received data and an analytical data set which complies with an oceanic phenomenon as an object can be generated. SOLUTION: Each received-signal series data which are inputted (11) to an oceanic-sound tomographic-data analyzer are stored once (1). By using an oceanic dynamical model (13), model received-signal data according to the oceanic phenomenon and a model error are calculated (12, 15). By using their calculated values, the Karman gain is generated. By using the Karman gain, the received-signal series data (16) is filtered. Thereby, the analytical data set which is suitable for the oceanic phenomenon as the object is obtained (17, 18).
