A new transform which combines the key features of the Radon transform and the wavelet transform is presented. This transform, developed in response to the problem of wake detection in open water synthetic aperture radar (SAR) images, has parameters for rotation in addition to spatial localization. Images with arbitrary positioned linear features are shown(More)
An iterative method that combines a parametric channel model with the maximum likelihood and cross-correlation estimation techniques has been developed to estimate the reflection, creeping wave, and times-of-arrival from an echo emanating from a rigid acoustic sphere. The modeled echo is assumed to have a generalized form, i.e., it is more complex than a(More)
