FIELD: radio engineering, communication.SUBSTANCE: distributed random antenna protection device has N interference generators (3) connected to the distributed random antenna through corresponding interface devices (2), and M nonlinear elements (4), where M is less than or equal to N, which are included in the distributed random antenna, wherein each of the M interface devices is connected to the corresponding nonlinear element, through which under the effect of M<N interferences, random integrated-differential frequency conversion of information signals and interference emitted by the distributed random antenna is carried out.EFFECT: high efficiency of protecting a distributed random antenna on confidential information leakage channels.4 dwg |
