Система радіоелектронного впливу на канали керування та відеозв’язку бпла із використанням квадрифілярної антени

Abstract

The paper proposes a method for generating radio interference against control and video transmission channels of unmanned aerial vehicles under combat conditions. The main focus is on suppressing signals in typical communication bands (433 MHz, 868/915 MHz, 1.2–1.3 GHz, 2.4 GHz, and 5.8 GHz) used for telemetry, control, and FPV video transmission. The method is based on the use of a quadrifilar loop antenna (QLA), which provides circular polarization and uniform azimuthal coverage, thereby increasing the effectiveness of interference against moving targets
