摘　　要：弹道目标(运载火箭、弹道导弹等)具有射程远、速度快、威力大等特点,极具战略威胁,随着攻防技术的此消彼长,弹道目标的防御正从被动段、中段向主动段延伸。尾焰作为弹道目标在主动段特有的现象,它的电离层扰动特性、RCS值增强特性、频域特性和红外特性是用来检测弹道目标的主要依据,在弹道目标的防御中具有十分重要的作用,其中"电离层扰动特性"的实时性较差,"RCS增加"是天波超视距雷达检测导弹目标的前提,"频域特性"可以用来确定弹道目标的位置信息,但是准确性不及"红外特性"。Ballistic targets（rockets and ballistic missles）have the features of long range,big acceleration and strong power.Along with the attactive weapons become stronger,the defensive system is extended from re-entry phase,midcourse to boost phase.The tail flame only exists in the boost phase of ballistic target.It is featured by ionospheric disturance,RCS value enhancement,frequency-domain characteristic and infrared radiant characteristic,which can be used to detect the ballistic target.The real-time characteristic of the ion-ospheric disturance is the worst.The RCS value enhancement is the prerequisite condition,which is used to detect ballistic target by over-the-horizon radar.The frequency-domain characteristic can be used to localize the ballistic target,but its accuracy is worse than the infrared radiant characteristic.
