It is shown, imitating hindrances constitute extreme danger to radio engineering systems of data transmission and served objects, involve information and material losses. The group of vulnerable radio stations is allocated. The expediency of such mode of communication at which detection of the fact of influence on the channel of this or that deliberate hindrance at the expense of introduction of set of the indicator functions generated by influence of hindrances is provided. The algorithm of an assessment of an alarm and interfering situation with use of information of indicators of accompanying signs is offered. The developed algorithm of an assessment of an alarm and interfering situation allows to reduce time of detection of the facts of influence imitating and to raise a noise stability of radio engineering systems of data transmission.
