Passive Stochastic Matched Filter: Application to Scuba Divers Detection
نویسندگان
چکیده
Due to its inherent discretion, passive detection is a convenient way for acoustic monitoring of maritime zone. In a context of harbour protection, one of the stakes is intruders detection e.g. scuba divers. However, the need for instantaneous reaction opens a field of research to improve the human operators’ detection tools. This article proposes a new approach of the SMF as a real-time passive detection method. The feasibility has been demonstrated on scuba divers signals recorded in a tank. This first tests show that the original SMF assumptions can be relaxed and that the use of this method can drastically improve the output Sound to Noise Ratio (SNR).

Target Detection in Bistatic Passive Radars by Using Adaptive Processing Based on Correntropy Cost Function
In this paper a novel method is introduced for target detection in bistatic passive radars which uses the concept of correntropy to distinguish correct targets from false detections. In proposed method the history of each cell of ambiguity function is modeled as a stochastic process. Then the stochastic processes consist the noise are differentiated from those consisting targets by constructing...
متن کاملPersonality profiles of recreational scuba divers
Although classified as an extreme sport, recreational scuba diving differs substantially from other forms of extreme sport. As a result, several researchers have theorized that scuba divers would display unique personality traits but little research has thus far been conducted regarding the issue. Previous investigations tended to group participants of different types of extreme sports together...
متن کاملSafety Priorities and Underestimations in Recreational Scuba Diving Operations: A European Study Supporting the Implementation of New Risk Management Programmes
Introduction: Scuba diving is an important marine tourism sector, but requires proper safety standards to reduce the risks and increase accessibility to its market. To achieve safety goals, safety awareness and positive safety attitudes in recreational scuba diving operations are essential. However, there is no published research exclusively focusing on scuba divers' and dive centres' perceptio...
متن کاملThe absence of hearing loss in otologically asymptomatic recreational scuba divers.
We undertook a retrospective cohort study of 16 experienced recreational scuba divers and 16 matched non-diver controls to determine the prevalence of hearing loss and, if present, the likely causes of this loss. Each subject was required to be aged 55 years or less and to have no history or likelihood of hearing loss. An audiologist, blinded to each subject's group status, undertook all examin...
متن کاملUnderwater human-robot interaction via biological motion identification
We present an algorithm for underwater robots to visually detect and track human motion. Our objective is to enable human-robot interaction by allowing a robot to follow behind a human moving in (up to) six degrees of freedom. In particular, we have developed a system to allow a robot to detect, track and follow a scuba diver by using frequencydomain detection of biological motion patterns. The...
