摘要:Abstract(#br)Constant-modulus signals such as m-sequences are known to have good autocorrelation properties, as well as good peak-to-average power ratio that allows for full utilization of the transmitter’s power. However, the broadband ambiguity surface for such signals exh...

摘要:Abstract(#br)We present a cooperative bathymetry-based localization approach for a team of low-cost autonomous underwater vehicles (AUVs), each equipped only with a single-beam altimeter, a depth sensor and an acoustic modem. The localization of the individual AUV is achieve...

摘要:Abstract(#br)A robust obstacle detection and avoidance system is essential for long term autonomy of autonomous underwater vehicles (AUVs). Forward looking sonars are usually used to detect and localize obstacles. However, high amounts of background noise and clutter present in u...

摘要:Most autonomous underwater vehicles (AUVs) are propelled by a single thruster, use elevators and rudders as control surfaces, and are torpedo‐shaped. Furthermore, they are positively buoyant to facilitate recovery during an emergency. For this class of nonhovering AUVs, ther...

摘要:In warm shallow waters, one can consistently hear the crackling sound due to snapping shrimp. An individual sound or “snap” is highly impulsive. Knowing the source locations of these snaps facilitates the development of some unique passive sensing applications. One common ap...

摘要:Underwater acoustic communications and networking technologies are critical tools for underwater exploration, subsea resource extraction, national defensemissions, etc. Their roles are becoming ever more important as nations around the globe turn to the oceans as sustainable sour...

摘要:We propose a multi-hypothesis solution to the simplified problem of simultaneous localization and mapping (SLAM) that ariseswhen only two measurement frames are available. The proposed solution is obtained through direct evaluation of the posteriordensity as given by finite set s...
