1. A method of localizing a moving body using a localization system having a plurality of sensors disposed at different places for receiving energy of radiation, such as acoustic waves, electromagnetic waves, etc., emitted by the moving body, and a moving body localization calculation device connected to said plurality of sensors said method comprising the steps of: estimating locations of said moving body using two different estimation methods, correcting physical parameters of said localization system, based on differences between the estimated locations estimated by said two different estimation methods, and calculating a location of said moving body on the basis of reception times of the radiation received by said plurality of sensors and the corrected physical parameters.
