Radar signature analysis using information theory

The ability to make radar signature databases portable for use within similar sensor systems is critical to the affordability of airborne signature exploitation systems. The capability to hybridize measured and synthetic signature database components will maximize the impact of the investment required to build complex radar signature databases. Modal mutual information is developed as a measure of similarity to compare measured field data to modeled synthetic data. The approach is demonstrated using synthetic signature sets comprised of both ldquosimilar targetsrdquo and ldquodissimilar targetsrdquo.
