Fourier descriptors are used to characterize the binary grey level silhouette images of ship targets. A grey level threshold technique is developed to determine the contour of the ship and comparisons are made between test shapes and library shapes using Euclidean distance as the match criterion. Binary grey level spot image comparisons are found to generate a suitable identification threshold which is successfully adapted to provide a ship silhouette identification threshold.
