An integrated applicative communication method designed to enhance underwater acoustic remote control on small unmanned underwater vehicles (UUVs) is presented. The frame structure and detection method are intended to improve the rate and reliability of communication under complex conditions of multipath, high velocity motion and strong jamming. The scheme consists of four fields, including synchronization...
Passive sonar arrays are often used to find submerged vessels by measuring their radiated signal. Acoustic vector-sensor (AVS) arrays, which are normally towed by the ship at the ends of long cables, have been proven to be very effective for target direction of arrival (DOA) estimation. The flow noise, arising from the flow of water over the vector-sensor or its housing when the array is towed, is...
