Abstract

A system for identification of aircraft is described. This system is intended to extend the use of a thermal imager. The system uses a hot spot detector for locating possible targets in the image and then performs the identification process within a small window centered around these detections. The identification system uses look-up tables for coordinate rotations and then applies a special transform, the Discrete Contour Transform, to make position- independent feature sets. These sets are then each fed to neural network classifiers. If the target is recognized by one of the neural networks a report is made, which includes the identification and its hit probability.
