FIELD: measurement equipment.SUBSTANCE: system (20, 30, 40) designed for monitoring of underwater area (10) includes a sensory assembly having the possibility of performing measurements at least with one physical variable in the above area (10) so that generation at least of one corresponding signal of the sensor is provided, and data processing device (170, 510, 520) intended to process at least one signal of the sensor to create the processed data for presentation and/or recording. Sensory assembly (20) includes one or more voltage sensors (190) made so that they can measure electric fields present in underwater area (10) and provide information in at least one signal specifying the availability of electric fields. Besides, sensory assembly (20) includes one or more hydroacoustic sound detectors (200) having the possibility of receiving sound energy created in underwater area (10) and adding the corresponding information at least to one of the above said signals of the sensor to communicate it to data processing device (170, 510, 520).EFFECT: improvement of the system.23 cl, 10 dwg |
