Design and Implementation of Remote Low Power Wakeup Mechanism for Underwater Acoustic Equipment

In order to reduce power consumption of underwater acoustic equipment(such as acoustic releaser. wireless sensor nodes, etc.), this paper puts forward a low-power signal detection mechanism on the basis of the matched filter noncoherent envelope detector, and a low false alarm rate signal detection mechanism on the basis of the Taylor orthogonal detector. Several hardware prototype for tone detection have been build and tested. Field tests shows the low power consumption and high reliability characteristics of the above two detectors which are more practical among the other methods.
