A new transform which combines the key features of the Radon transform with the localization abilities of the wavelet transform is presented. The transform was developed in response to the problem of wake detection in open water synthetic aperture radar (SAR) images. Consider the fact that wakes are generally small in size relative to the original SAR image. Further, ship wakes have linear features. So even though the orientation and size of the wake is unknown a priori, a transform which has parameters for rotation and spatial localization may aid in the detection of these features.
