| Abstract: | In electro-optical countermeasure environment, the variation of radiant energy of IR flare is very acute. The ant jamming IR seeker demands the dynamitic change of radiant energy of IR flare to be reflected in real time to meet the requirements of amplitude discrimination and amplitude correlation. The main amplifier demands a high rapidity in AGC. It is introduced that the principle and peffermance of the fast feedward AGC circuit and the computer gain control circuit in this paper. The characteristics of several AGC circuits are also compared. |
