This paper focuses on optimal time-of-arrival (TOA) sensor placement for multiple target
localization simultaneously. In previous work, different solutions only using non-shared …

Underwater acoustic communications are limited by the following channel impairments: time
variability, narrow bandwidth, multipath, frequency selective fading and the Doppler effect …

Since the Cramér-Rao lower bounds (CRLB) of target localization depends on the sensor
geometry explicitly, sensor placement becomes a crucial issue in many target or source …

The accurate detection and quantification of submerged targets has been recognized as a
key challenge in marine exploration, one that traditional census approaches cannot handle …

The bearing estimation problem of low-frequency underwater acoustic sources is of
paramount importance in antisubmarine warfare and passive acoustic monitoring …

Conventional active sonar systems transmit a high power and low refresh rate signal to keep
high power echoes from detected targets and maintain an effective detection range …

This article describes the development and testing of a passive sonar, multitarget tracker,
and adaptive behavior that enable an autonomous underwater vehicle (AUV) to detect and …

Detection and tracking of underwater target play an important role in enhancing the marine
sensing ability. Currently, the above mission is usually conducted in a single platform, and …

Cooperative autonomy and data sharing can largely improve the mission performance of
robotic networks in underwater surveillance applications. In this paper, we describe the …

In the multi-sensor localization problem, selecting sensors strategically to form an effective
geometric configuration is crucial for enhancing both localization accuracy and system …
