FIELD: reduction of radar signature of antenna systems.
SUBSTANCE: controllable absorbing screen of the antenna system includes radio-transparent dielectric walls forming a sealed radio-transparent cavity, with the ability to control its properties of absorption of electromagnetic waves by filling the sealed radio-transparent cavity with absorbing liquid, while a membrane partition or corrugated structure is installed in the screen cavity, and elements of a frequency-selective structure are installed on its walls.
EFFECT: providing the ability to reduce the radar signature of antenna systems.
