非触发无线电引信是反雷达导弹的组成部分,其特点在于不需要同目标接触,而对日标的某个特性或环境一定地反应引爆战斗部。作为非触发无线电引信设备的基础可能是各种物理现象,像电磁波辐射、热辐射、放射性、声振动、静磁和静电现象以及气压变化等等。 电磁波辐射被应用的最广泛。如果用引信辐射的电磁波照射日标,则称此引信为主动式引信。如果用地面雷达照射反雷达导弹,则称半主动式引信。按雷达站的非主要辐射工作的引信称为被动式引信。但是,如果用自然界能源(例如太阳)照射目标,则称为半被动式引信。
Non-triggering radio fuzes are an integral part of anti-radar missiles and are characterized by the fact that they do not need to be in contact with the target, but must react to a certain characteristic or environment of the superscript to detonate the warhead. Fundamentals of non-triggering radio fuze devices can be various physical phenomena such as electromagnetic radiation, thermal radiation, radioactivity, acoustic vibrations, magnetostatic and electrostatic phenomena, and changes in barometric pressure. Electromagnetic wave radiation is the most widely used. If the use of fuze radiation electromagnetic radiation standard, then the fuse is called the active fuze. If ground radar is used to illuminate anti-radar missiles, semi-active fuses are said to be used. Fuze by non-main radiation work of radar station is called passive fuze. However, if the target is irradiated with natural energy (such as the sun), it is called semi-passive fuze.
