Abstract
A real-time recurrent learning algorithm was applied to a five class radar target identification problem. Wideband radar signatures were generated for five aircraft classes. Since an aircraft in flight is constantly in motion, a radar can measure sequences of radar signatures as the aspect angle changes. A radar can also generate aspect angle estimates by using kinematic information from aircraft position and velocity measurements. A recurrent neural network computer program (implementing a real time recurrent learning algorithm) was trained to recognize these sequences of radar signatures. Each radar signature was described by 6 external input features: the estimated target azimuth, the estimated target width, and 4 noisy amplitude values from 2 peak range bins. Nine consecutive radar signatures were sufficient to achieve a test set accuracy of 96%.
