On the Use of a FHSS Modulated Signal in Multi-Users Underwater Detection Context

Résumé

In order to detect and locate a receiver relative to a grid of transmitters in an underwater environment, it is necessary to detect each signal emitted by each transmitter and estimate its Time Of Arrival (TOA) and estimate the position through triangulation. The choice of the signals and their modulation is then crutial to have a good estimation of the TOA and reduce false alarms. This paper focuses on FHSS (Frequency Hopped Spread Spectrum) modulations and compares the performances of several codes, by using a criterion proposed in this paper. It proposes finally to adapt the best FHSS signal in a multi-users context.
