末敏弹红外辐射特性及探测

Infrared radiation characteristic and detection of the terminal-sensitive projectile

末敏弹作为一种新型攻击坦克装甲目标的武器,已成为国内外发展的重点弹药。对末敏弹进行探测,采取必要的应对措施,对于提高坦克装甲目标的生存几率具有重要意义。在介绍末敏弹工作原理的基础上,分析了末敏弹的红外辐射特性及其探测方法。结果表明:由于末敏弹载体不同,从而使末敏弹的初速差别很大,其红外辐射的峰值波长随初速的增加从长波红外波段移向中波红外波段,在探测末敏弹时,要根据末敏弹红外辐射特性和探测器的响应特性选择探测器,而且在探测时,由于末敏弹为弱小目标,要求探测系统具有较小的瞬时视场。

The terminal-sensitive projectile is a new kind of ammunition to attack tanks and armors,which is being developed by many countries.Detecting it and adopting countermeasure are useful for reducing the kill probability of the terminal-sensitive projectile.On the basis of the working principle and the attack process of terminal-sensitive projectile,its IR radiation characteristic and corresponding detect technique are studied.For different carrier,the muzzle velocity of the terminal-sensitive projectile is quite different.The radiation peak wavelength shifts from long wavelength region to middle wavelength region along with the velocity increasing.The detector should be chosen according to the detector′s response characteristic and the terminal-sensitive projectile infrared radiation feature.Analysis also suggests a small instantaneous field of vision（IFOV） because the target is dim.
