Testing and evaluation is essential for the modification and installation DIRCM onto an aircraft. DIRCM is an optical device that deceives infrared guided missiles. There are many things to consider when installing DIRCM on an aircraft and operating it. In order to verify the function and performance of DIRCM, the characteristics of the linkage equipment were presented, and the expected flight sortie was proposed by specifying the test and evaluation methods, items, and detailed test conditions.

The function of DIRCM(Directed Infrared Countermeasures) jamming is to cause the missile to miss its intended target by disturbing the seeker tracking process. The DIRCM jamming uses the pulsing flashes of IR energy and its frequency, phase and intensity have influence on the missile guidance system. In this paper, we analysis the DIRCM jamming effect of spin-scan reticle seeker. Simulation results show that the jamming effect is greatly influenced by frequency, phase and intensity of the jammer signal.
