Abstract: A new improved parameterization means of instantaneous signal is proposed. Its applications in the field of nuclear ex plosion detection are presented. The discus-sion will centre on the signal modelling and the algorithm of extracting signal parameter. Finally, some typical instances which apply to the field of nuclear explosion recognition and itscomputer simulations are given. -
