Air Vehicle Detection by Using an Ensemble of Moving-Picture Images.
Abstract
This document examines three-dimensional matched filtering and shows how it can be applied to accomplish target detection over sequences of observed scenes, which is an important extension of classical two-dimensional image processing examples to demonstrate and validate these results are provided. Three-dimensional filtering techniques can be easily modified to act as a space-shift, time-delay-and-integrate matched-filtering technique. Computer simulations verified the validity of this modification. The results demonstrate signal-to-noise ratio gains asymptotically growing by the filter integration time over those normally obtained by two-dimensional matched filtering of the individual frames in a sequence. The specific form of the output is ideally suited for moving-target indicator (MTI) applications, or can be used in conjunction with some other target-speed and detection-localizing algorithm.
