历来的近炸引信都是利用无线电波,根据目标体积大小来决定弹丸起爆位置。这个方式往往会出现由于目标的大小不同与形状的不同而改变起爆位置。对于反射量大的目标会出现早炸;对于反射量小的目标则会出现晚炸现象;存在着引信不受导弹速度和目标速度限制而决定起爆点的缺点。另一种电波近炸引信的起爆方式则是,当导弹通过目标的正侧面时,多卜勒频率为“0”(淹没点),检波出此点作为起爆点。这一方式只有在导弹的弹丸破片速度极大地超过目标速度时才有效。对于超音速的目标是没有作用的
All the usual near-fuze are the use of radio waves, according to the size of the target volume to determine the projectile initiation position. This method often appears due to the size of the target and the different shape and change the initiation position. For the large amount of reflection of the target there will be early frying; for the small amount of reflection of the target will appear late frying phenomenon; there is a fuse without the missile speed and target speed limit the shortcomings of the initiation point. Another approach to initiation of near-fuse fuzes is to have the Doppler frequency “0” (submerged) as the missile passes the positive side of the target, detecting this as the initiation point. This method is effective only if the projectile fragment velocity of the missile greatly exceeds the target speed. For the purpose of supersonic no effect
