The issue of increasing the noise immunity of special purpose radio systems operating in a complex electronic environment is an urgent and unresolved problem in its entirety. One of the possible ways of increasing the noise immunity of special purpose radio communication systems is to increase the accuracy and speed of assessing the state of the communication channel in a dynamic signaling and interference situation. In this work, an analysis of existing methods for assessing the status was made, it was found that existing methods do not allow for multicriteria assessment of the quality of communication channels with acceptable computational complexity and reliability of decision-making. The methodology of multicriteria estimation of the quality of communication channels of special purpose radio communication systems, operating in a complex electronic environment, was developed. The article proposes to use a fuzzy logic device for conducting multicriteria assessment of the quality of communication channels due to deliberate interference and silence of the signal. The essence of the proposed methodology is to carry out an assessment of the state of communication channels of special purpose radio systems for each of the indicators of evaluation, after which a generalized assessment of the state of the communication channel is formed. Also, in the proposed method, the correction of the weight of expert rules is carried out, which allows to increase the speed and quality of the assessment of the state of the channels in a dynamic signaling and interference situation. The obtained results should be used in radio communication with programmable architecture, in order to increase the speed and accuracy of the assessment of the state of communication channels.
