Abstract EN
This work, under the optimal experimental design framework, investigates the sensor placement problem that aims to guide electromagnetic induction (EMI) sensing of multiple objects.
We use the linearized model covariance matrix as a measure of estimation error to present a sequential experimental design (SED) technique.
The technique recursively minimizes data misfit to update model parameters and maximizes an information gain function for a future survey relative to previous surveys.
The fundamental process of the SED seeks to increase weighted sensitivities to targets when placing sensors.
The synthetic and field experiments demonstrate that SED can be used to guide the sensing process for an effective interrogation.
It also can serve as a theoretic basis to improve empirical survey operation.
We further study the sensitivity of the SED to the number of objects within the sensing range.
The tests suggest that an appropriately overrepresented model about expected anomalies might be a feasible choice.
