Abstract
Laser beam is directional and small in divergence angle so that it is well qualified to deliver high intensity infrared energy into a coming MANPADS threat for aircraft survivability. The threat will be deceived and loose tracking of a target when it is exposed to the laser beam modulated relevant to the track mechanism of the threat. The laser beam goes through scattering inside the seeker of the threat and reach the detector in a stray light form, which is a critical phenomenon enabling jamming of the seeker. The mechanism of the laser beam based jamming against a pulse modulated infrared seeker is shown. Simulations are carried out to support the understanding of how the jam technique works.
