At work of systems frequency AFT take place instability of parametres of the frequency discriminator. It leads to decrease in quality of frequency trim. In article the Simulink-model of search system frequency AFT survey radar which allows to investigate influence of asymmetry of shoulders of the frequency discriminator on quality of frequency trim is offered. Character of change of a strip of capture from a difference of factors of strengthening of shoulders of the frequency discriminator is investigated.
Keywords: automatic frequency trim, the frequency discriminator, a capture strip, Simulink-model
