A wide variety of radar-based ATR systems and applications have been developed and documented in open literature. As different as these may seem on the surface, they all tend to revolve around four basic steps, labeled in this chapter as the unified framework for ATR. First, the target set must be identified. Then the feature set must be selected, observed, and tested to identify the targets. The most challenging parts of the problem tend to be predicting all likely target variations and discerning a feature set that sufficiently segregates the target set while being readily observable.
