STA/LTA Detector

The STA/LTA Detector program is a representation of a detector of various events in triaxial or single-component time signals. The software is based on one of the STA/LTA detector types.

STA/LTA Detector can be used for detecting any events accompanied by a short-term increase in the input signal amplitude, e.g.:

  • seismic events;
  • explosions of various nature;
  • events expected during safeguarding activities;
  • various structures initial defects detection (using acoustic emission).

The figures below show the results of the STA/LTA Detector software operation when reproducing the signals of the 5.0 magnitude earthquake which took place on March 16, 2011. The earthquake was registered by the BC  1313 sensor located approximately at a distance of 210 km from the earthquake focus.
