ABSTRACT:
A sensor manager comprising: a situation information expected value network and an information instantiator. The situation information expected value network includes a probabilistic network configured to generate situation probabilities using situation data; and an expected information gain determination module configured to generate an information request using expected changes in the situation probabilities. The information instantiator is configured to generate a sensor observation request utilizing the information request and the situation data. The situation data includes at least one of the following: a goal lattice structure data; a goal lattice value; a kinematic state estimate; a non-kinematic state estimate; a search probability mass function; a sensor applicable function table; or any combination of the above. The probabilistic network includes: at least one managed evidence node; at least one unmanaged evidence node; and at least one situation evidence node.
