A method of attaining a linguistic goal output of a process using a linguistic goal oriented decision making system, comprising setting the output value to a linguistic goal, and establishing a set of descriptive rules using historical data, wherein each descriptive rule has at least one variable, a decision variable, and at least one linguistic output value. The method further comprises grouping the set of descriptive rules into subsets of descriptive rules according to the linguistic output value of each descriptive rule and establishing decision rules based on comparing the grouped subsets of descriptive rules, the one or more decision rules describing a modification of a decision variable associated with at least one of the descriptive rules to affect the process.

Linguistic goal oriented decision making

The invention includes an arrangement of actual sensors in an antenna array with a computation of higher-order statistics to provide virtual second order statistics corresponding to virtual elements in the array; employment of the actual and virtual elements of the array for covariance based direction finding; and, with the addition of a separate sensor spaced from the main array, suppression of non-Gaussian measurement noise. This is accomplished employing cross-correlation of the virtual sensors or alternately calibrating the existing actual array employing cross-correlation of the array and it's virtual sensors.
