This paper proposes a new scientific approach to determining the stability conditions for processes aimed at detecting technical means of unauthorized information acquisition (TMAIA) under the influence of deliberate jamming. It is shown that the stability of an intelligent system for detecting intentional jamming depends on the delay time, which is accounted for by a system of delay differential equations describing the inertia of monitoring channels, signal processing delays, and the adaptive dynamics of parameters characterizing the presence of in tentional jamming. To analyses the stability of the system, the Rychlinski oval is used as a tool for investigating the spectral properties of the characteristic quasi-polynomial of systems of differential equations with delay. A new stability condition for detection processes (SPV) is obtained in the presence of variable delays and active countermeasures by the attacker. An analytical and numerical analysis of the system’s dynamics has been carried out, demonstrating the regions of stable and unstable operation of the intelligent detection module.Prombles in programming 2026; 2: 67-76
