By use of some eigenvalues such as missile launch location , infrared radiation of boosting missiles plumes and missile engine off - time eigenvalue , data fusion based on weight sum of membership degree is applied to deduce the type and launching country of the missile 該算法提出用導(dǎo)彈發(fā)射點(diǎn),位置、導(dǎo)彈尾焰紅外特徵和導(dǎo)彈關(guān)機(jī)點(diǎn)特徵量作為導(dǎo)彈目標(biāo)識別的特徵量,用模糊隸屬度加權(quán)求和方式進(jìn)行信息融合,根據(jù)融合和最大融合量的閾值判決確定導(dǎo)彈的類型、國別。
