      <abstract>
        <p>This article proposes the application of a closed-loop algorithm for electronic warfare means intended to counter analog FPV-UAV video channels. The system-level contribution is the integration of SDR-based radio monitoring, signal-parameter estimation, OSD-assisted classification, selective multi-frequency interference scheduling, and post-action channel monitoring within one information cycle. The individual detection and interference techniques are not claimed as new; the proposed contribution lies in their coordinated control logic and feedback transitions. A conditional-probability model and a response-time model are used to describe error propagation and delay. Because no comparative field-test or simulation dataset is reported, the expected gains in efficiency and response time remain hypotheses for future validation. The approach is presented as a conceptual basis for adaptive SDR systems.</p>
