When monitoring spatial phenomena, we are not just interested in measurements at sensed locations but also at locations where no sensors were placed. To estimate the scalar field where no sensors are deployed, we need to interpolate the data. We are interested in how the best sampling design is to be found and best used to draw conclusions about the field(More)
The architecture has always been one of the key aspects for designing an unmanned underwater vehicle. The architecture should serve as an aid, not a burden, in the integration of modules that have been developed independently, so it must not be overly restrictive. In this article, three types of architectures (deliberative, reactive, and hybrid(More)
To improve the tracking accuracy of an underwater maneuvering target, according to its characteristics of low speed and weak maneuvering performance, an adaptive Kalman filter is given based on the online estimation of the process noise variance. As the main filter analyzes the target motion, the process noise variance of the main filter is estimated by an(More)
The H<inf>&#x221E;</inf> filtering problem is considered for a class of nonlinear discrete-time systems for which a novel solution is developed by embedding the unscented transform technique into the extended H<inf>&#x221E;</inf> filter structure. This article compares a Scale Unscented Transform H<inf>&#x221E;</inf> filter (SUT H<inf>&#x221E;</inf> - ) and(More)
A semi-physical simulation framework for multiple unmanned underwater vehicles' (UUVs) coordinate operation, which can complete large-scale reconnaissance in civil, academic military application, is presented. The structure of simulation framework consists of virtual environment unit, vision display unit and UUV control unit. The primary motivation of this(More)
Unmanned underwater vehicles have various missions within civilian, military and academic sectors. They have the ability to explore areas unavailable to manned assets and to perform duties that are risky to humans. In particular,UUVs have the ability to perform bearings-only tracking in shallow areas near shorelines. This article compares a Logarithmic(More)
