Vibroacoustic Control and Surveillance System TOPOT

1/1

The vibroacoustic control and surveillance system is intended for all-weather, round-the-clock automatic detection, identification, tracking, and measurement of coordinates and parameters of any moving objects on the surface of the controlled area. The system can be also used to protect the perimeter and extended objects from trespassing.

 

The functioning of the system is based on the recording of surface acoustic impacts within a wide frequency range using a distributed vibroacoustic sensor: an optical fiber installed in the ground at a certain depth along the expected area of impact.

Upon processing primary measurement results, a graphic indication of the propagating acoustic wave is formed. Based on the constructed wavefront pattern the spatial coordinates and movement speed of an object or objects creating vibratory impacts are determined, which makes it possible to automate the observation. The system can simultaneously detect several objects, provided they are separated from each other by a distance exceeding the spatial resolution of the system.

Functions:
  • automatic detection of moving objects on runways and taxiways

  • determination of coordinates and trajectory parameters of moving objects

  • separate tracking of moving objects and building their trajectories

  • identification of moving objects based on the principle of «Propeller Plane – Jet Plane – Vehicle»

  • recording of take-off and touchdown points on the runway

  • detection of a runway/taxiway overrun

  • generation of information and its issuing to users via approved protocols

  • documenting of coordinate and trajectory data from objects moving on the runway and taxiway

  • intrusion localization

  • real-time control of the system’s technical state

  • archiving and storage of system operation results

Advantages:

  • flexible system architecture that allows its expanding and augmenting at any time, as well as implementing different types of sensors for round-the-clock surveillance

  • increased jamming immunity – system operation is not affected by electromagnetic fields, electrical discharges and environmental conditions

  • high sensitivity and high accuracy of locating an event

  • continuous analysis of the object’s state, instantaneous reaction to the event

  • possibility of using redundant optical fibers of the sensor cable for data transfer, control of adjacent systems, backing-up of communication and data transmission networks

 

Interface:

In the standby mode the system status information is displayed on the workstation monitor. When a warning signal is received, the monitor screen automatically displays video information indicating the location and number of the alarm zones. This information is duplicated by a voice message output.
