摘要

Abstract: Model-based and data-driven approaches to automatic target recognition each provide a methodology to determine the class of an unknown target. Model-based recognition is a goal-driven approach that compares a representation of the unknown target to a reference library of unknown targets. A comparator algorithm determines a degree of `match' to each reference target. Data-driven approaches use a numeric algorithm to process a set of characterization features to produce a class likelihood estimate. Each approach has advantages and limitations that should be considered for a specific implementation. This research compares a specific implementation of each of these approaches developed for an automatic target recognition system that processes multi- spectral imagery representing military targets. To provide a valid baseline to compare the performance of each approach, a common target set, characterization feature set, and performance metrics are considered.!18
