In recent years, researchers have addressed the problem of using noncoherent approaches to estimate pulse width and repetition interval. Since measured transmitter is noncooperative, integration gain can be realized, input signal-to-noise ratio (SNR) for these estimators becomes critical. We examine multiple edge detectors that exploit moving sums calculated as part a Haar filtering received si...

SAR interferometry has developed rapidly in recent years and now allows measurements of subtle deformation the Earth's surface with millimeter accuracy. All state-of-the-art processing methods require a precise coherence estimate. However, this estimate is random variable biased toward higher values. Up to now, little published on Bayesian estimation degree coherence. The objective paper...

the goal of multi-frame super resolution (sr) is to fuse multiple low resolution (lr) images to produce one high resolution (hr) image. the major challenge of classic sr approaches is accurate motion estimation between the frames. to handle this challenge, fuzzy motion estimation method has been proposed that replaces value of each pixel using the weighted averaging all its neighboring pixels i...
