In some known works devoted to the jamming resistance of data link with pseudorandom operating frequency agility in the conditions of the worst jamming located in a bandwidth part the barrage jamming (noise) activity in the whole bandwidth is being
neglected. However jamming situation assessment shows the possibility of the simultaneous activity of two powerful enough jamming types: the worst jamming in a bandwidth part and the broadband barrage jamming. That is why the authors get a new analytic form to count the optimal for suppression (determining the minimal jamming resistance of the data link) value of the frequency bandwidth part affected by localized jamming at the simultaneous broadband barrage jamming activity. This optimal value differs significantly from the known value estimated without taking into consideration broadband barrage jamming activity.
