Anti infrared interference information processing method of the infrared angular instrument;

This paper briefly introduced the composition theory both in hardware and software of the infrared angular instrument using L-shape reticle, discussed the anti infrared interference software algorithm of the infrared angular instrument.

Seven kinds of antijamming methods,such as time correlated choice and field-of-view shrinkage, inertial track,real-time memory criterion,amplitude discrimination, pulse-width discrimination, pulse-amplitude time sequence discrimination and pulse-width amplitude discrimination for Counter-Infrared-Interference-Missile(CIRIM) with the cross-shaped detector array are given.

Influence of infrared jamming on portable air defense missile;

Penetration of the ballistic missile in infrared wavebands is achieved mainly by controlling the infrared signatures of its warhead and by implementing infrared jamming to the interceptors.

Some advanced infrared countermeasure technologying, such as infrared warning, infrared jamming, DIRCM, infrared decoy, infrared smoke screen and infrared stealth are used to resist the threat of infrared guided missile.

Principles and performance parameters of infrared countermeasure bombs were discussed.

Finally,the countermeasures of pre-alarm of missile attack,IR stealth of airplanes,IR decoy flare,IR smoke screen,IR jamming plane and laser anti-missile technology are elaborated,and their trend is expected.
