  VEHICLE DETECTION METHOD IN SENSITIVE ZONE OF PASSIVE ACOUSTIC TRANSPORT DETECTOR

  05.00.00 Technical science

  Tags: mathematical model moving object detection passive acoustic transport detector threshold method
  Description

  In this article, transport detection method in sensitive zone of passive acoustic transport detector is considered. The transport speed estimation by acoustic data principle is described, an analytical survey for moving object detection is performed, and the mathematical model of described transport detector is investigated. As the result of this work, a transport detection criteria using acoustic data is suggested
