Stationary system of passive monitoring of sea water area “KLIVER 1”
- Reception, processing and classification of acoustic signals for detection underwater objects
- Detection of surface objects;
- Coastal barrier line of the underwater surveillance system;
- Round-the-clock surveillance under water;
- Protection of the coast, naval bases and ports, oil platforms and water areas that require special attention;
- Monitoring of tsunami threats, monitoring of currents, temperature and salinity
Control point
- Automated data processing and analysis system
- Communication system:
- Radio channel;
- Fiber optic cable;
- Fiber optic cable;
System location characteristics
- The depth of the sea at the location of the station is from 40 to 200 m.
- The intensity of swimming in a zone with a radius of 4 km from the installation point stations, a maximum of three vessels at the same time.
Characteristics of modern low-noise submarines detected by a narrow-frequency channel
- speed of movement
- not less than 2m/s (4 knots)
- Water capacity
- not less than 1000t
- Reduced noise level of underwater target to 1m
- not less than 0.05 Pa per 1 kHz in the Hz range
- Environmental noise spectrum level in the working range of 10 - 100 Hz
- not less than 0.1 Ra at each of the frequencies
Main Features
- Accuracy of setting the object with errors that do not exceed the characteristics listed above
- +-5 (confirmed by test results)
- Range for an object with the above characteristics
- not less than 4km (confirmed by test results)
- Probability of correctly classifying the target as an underwater object or a surface vessel
- not less than 0.95 (confirmed by test results)
- Transfer of information to the shore station
- It is carried out using a connection: underwater sound; radio Buick; fiber optic;
- Range of radio transmissions from the radio buoy to the shore station
- at least 50 km (calculated depending on the height of the location of the radio receiving antenna)

- Current speed
- up to 2 m/s
- Sea water temperature
- From 0"С to +35'С
- Limited ambient temperatures to install station
- -28'С to -50'С
