A PARAMETERIZATION MEANS OF NUCLEAR EXPLOSION SIGNAL AND ITS APPLICATION
-
摘要: 本文提出了一種經(jīng)過改進(jìn)的瞬態(tài)信號參數(shù)化方法并討論了這種方法在核爆炸探測領(lǐng)城內(nèi)的應(yīng)用。重點(diǎn)闡述了信號建模及參數(shù)提取的計(jì)算方法,最后給出了本方法在核爆炸識別中的典型實(shí)例及計(jì)算機(jī)仿真結(jié)果。

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. -
