Recently introduced Stretched Modulation Distribution is used to study tolerance to non-idealities in time bandwidth engineering systems that employ nonlinear phase operations. In particular, the performance in far field and near field regimes is determined by group delay ripples at lower and higher frequencies, respectively.
We describe a new computational approach to edge detection. Our digital algorithm emulates propagation of light through a physical medium with specific nonlinear diffractive property. The method uses the phase profile of the output complex-amplitude image to identify the edges with different strength in a digital image. This technique is related to the recently introduced Discrete Anamorphic Stretch...
Remote Sensing techniques are powerful tools for many civilian and military applications. However, in many cases high spatial, radiometric and temporal resolutions are required, leading to a large amount of data to be transmitted and/or stored. Synthetic Aperture Radar (SAR) is able to produce high resolution coherent images of a scene in any light and weather condition. In this paper we introduce...
