Spanning Sensor Resource Management
Abstract: This paper presents multiple
applications of sensor resource
management. The general focus
entails two chapters on adaptive
estimation of time-varying sparse
signals and three chapters exploring
autonomous control of unmanned
aerial vehicles (UAVs) sensor
platforms employed for target tracking.
All of the included applications are
posed as decision control problems
formulated in the rigorous framework
of a partially observable Markov
decision process (POMDP) and
solution methods based on Bellman's
equation are exercised, generating
adaptive control policies for action
selections in the given scenarios.
Specifically, the rollout optimization
method is administered in the cases of
signal estimation under the objective
of maximizing the information gain
about the unknown sparse signal. For
the UAV sensor platform control,
nominal belief-state optimization
(NBO) is employed for control
selection for optimizing objectives
including target-tracking error,
surveillance performance and fuel
efficiency. The empirical studies in
each investigation present evidence
that non-myopic solution methods,
accounting for both the immediate and
future costs of the current action
choices, provide performance gains for
