Integrating over sea radio channel for sea turtles localization in the Indian Ocean

Abstract

Abstract-This paper deals with the modeling of over sea radio channel with the aim of establishing sea turtle localization off the coast of Reunion Island but also on Europa Island in the Mozambique Channel. In order to model this radio channel, we are making a measurement protocol. In a first approach, measurements of turtle trajectory were done over land and finally it will be conducted over sea. We have scheduled an over sea measurement campaign in the middle of June. This paper shows a signal cross correlation technique used to characterize the over sea propagation channel.

“…Then we could estimate the received power p r and the propagation's delay T p of the main path shown in figure 5. In order to highlight the main path we represent the radio channel's profile with its normalized power [3]. To finish, the couple (p r , T pi ) is sent to the POA localization algorithm.…”

“…In order to better understand or apprehend errors on the estimation of the trajectory of the turtles, it is essential to know first of all the biology of the animal and then in a second time to model and to correctly integrate the physical parameters of the channel radio transmission [3]. Thus, from the biological perspective sea turtles swim at different speeds.…”
