This article presents a method of the automated control of distributed radio direction finding system (RDFS) providing the construction of an automated system of technical diagnostics and recovery of distributed RDFS performance on the specified requirements. This dual-circuit method includes diagnosing and reliability operations, redundancy recommendations, and also control algorithms of the constituent elements of the system. The structure and mathematical apparatus of the operations, recommendations, and algorithms of the proposed method are shown. The basic requirements and restrictions under which the construction of automated technical diagnosis system is carried out are specified.
