Pospelov B. Adaptation of aviation radiosystems under conditions of situational uncertainty.

exchange in the radio engineering systems in real operation conditions with taking into account interferences. A research purpose is development of theory and methodology of providing information exchange in aviation radio engineering systems in situation ambiguity on basis of adaptive approach. The used methods are statistical theory of radiosystems, optimization, stochastic programming, adaptation and statistical design. The fundamentals of theory of providing information exchange in conditions of ambiguity and substantial change of signal-interference situation in case of a limited frequency-power resource of aviation radio engineering systems are created, which are based on the use of dynamic tracts of transmission with joint and separate adaptation of directivity patterns transmission and receiving sides; the mathematical models of the adjusted dynamic tracts of transmission are first obtained; the methodology of joint and separate adaptation of dynamic tracts of transmission for different levelsof structural and situation ambiguity is first developed; the approach to forming reference signals has got further development, based on the use of spectral redundancy of information signals. Pre-conditions for a new strategy of design of the aviation radio engineering systems functioning in the conditions of quickly changing signal-interference situation and geometry of systems are created. Level of introduction is interbranch. The sphere of the use is organizations that solve the tasks of providing the functioning of radiosystems and complexes in unknown indefinite and substantially unstationary interference situations.
