Abstract
A target detection system and method is disclosed that uses a trained detection component and an untrained detection component that enhances image data for candidate target detection. The trained detection component separates candidate targets from clutter within the image data using correlation filters trained from an image library. The image library includes target and clutter images that are used to tune the correlation filters. The untrained detection component separates the candidate targets from the clutter by suppressing clutter using a Fourier frequency transform of the image data. Anomalies are detected in the frequency domain, and retained to highlight candidate targets.
