METHOD FOR ELECTROMAGNETIC PROTECTION OF PREMISES |
摘要 |
FIELD: radio engineering; protection of premises against unwanted access to secret information. ^ SUBSTANCE: electromagnetic protection of premises is provided by means of shielding chamber whose walls are made in the form of three-layer metal-insulator-metal structure inserted between metal layers; insulator is divided into cavities isolated from one another by walls covered with double-ended radio-absorbing coating, electromagnetic radiation interference being provided within each cavity. In addition, similar radiation intensity of secret-information containing signal is afforded and masking interference acting in case of poor shielding of premises is ensured. ^ EFFECT: enhanced reliability of secret information active protection. ^ 1 cl, 4 dwg
