Signal processing using a multi-dimensional look-up table.

摘要

A series of discriminants may be applied to a multi-dimensional look up table with a view to making a decision on what the combination of discriminant values represent. The discriminants might be say phase, amplitude and polarisation of a radar return from a possible target. To reduce the number of look-up table dimensions and render the decision process more efficient, the discriminants are subjected to spectral decomposition to produce a reduced number of output discriminants which nevertheless may, given certain maximum entropy optimisation concepts, contain all the information required for the decision.
