FIELD: radio-engineering, communication.SUBSTANCE: guarding system is intended for use at water areas, lakes, in river streams and channels. Use in the system of the direct information transmission via the border water-air ensures prompt deployment of the guarding system in the monitoring zone without cables routing on bed and without radio beacons use on the water surface thus excluding possibility of the unauthorized external effects on the system.EFFECT: increased reliability and efficiency of the guarding system, simplification and cheapening of the transmission to the receiving point of the underwater situation information under complicated conditions of underwater monitoring and guarding measures at real water areas.2 dwg |
