Airplane missile defense system

The invention relates to an airplane missile defense system for smashing missiles or enemy planes striking at the rear part of an airplane. The airplane missile defense system comprises a rear view radar, a special backward aerogun and a special missile. The rear view radar is used for observing, targeting an object at the rear of the airplane and directing the missile. Radar guidance is unnecessary if infrared guidance is used for a homing missile. The aerogun is used for launching the missile in a pipe, solving zero-crossing velocity when the missile is launched backwards; causing the missile to complete the process of zero-crossing velocity in a gun bore to travel forward after the missile is out of the gun bore, and ensuring the stability of missile flight. The rear part of the missile is made into a gun shell form so as to be suitable for aerogun launch. When the airplane is chased by the enemy plane or stricken by the missile, the distance is so near that a short-distance micro-missile can be adopted, thus solving the problem that the existing air-to-air missile can not be launched backwards, greatly lowering the technical difficulty of over-the-shoulder launch and improving airplane survivability in wars.
