Methods for automatic detection of ships and ship wakes in digital SAR images were developed. Accurate pixel location algorithms with digital maps are used to distinguish sea from land. A Wiener filter and a high pass filter are employed to enhance potential ship targets. With an appropriate choice of threshold, all ships visible to the human eye are detected. More rapid filters using statistics were also developed. By analyzing the statistics of the backscatter scan around each ship candidate, the various types of wakes may be detected with a very high probability.
