Progress in Polar Oceans Research Using ERS - 1 Data
Data from IRS-1, especially from the AMI Image Mode, or SAR, have been particularly useful in providing data on ice type and motion and oceanic mesoscale featuxes. These data have been used in studies of ocean and ice circulation, climate processes, mesoscale processes near the ice edge, freshwater fluxes, and convection, and have also proved useful in support of operations in ice covered seas,
متن کاملthe clustering and classification data mining techniques in insurance fraud detection:the case of iranian car insurance
با توجه به گسترش روز افزون تقلب در حوزه بیمه به خصوص در بخش بیمه اتومبیل و تبعات منفی آن برای شرکت های بیمه، به کارگیری روش های مناسب و کارآمد به منظور شناسایی و کشف تقلب در این حوزه امری ضروری است. درک الگوی موجود در داده های مربوط به مطالبات گزارش شده گذشته می تواند در کشف واقعی یا غیرواقعی بودن ادعای خسارت، مفید باشد. یکی از متداول ترین و پرکاربردترین راه های کشف الگوی داده ها استفاده از ر...
Neural network wind retrieval from ERS-1 scatterometer data
This paper presents a neural network methodology to retrieve wind vectors from ERS1 scatterometer data. First a neural network (NN-INVERSE) computes the most probable wind vectors. Probabilities for the estimated wind direction are given. At least 75 % of the most probable wind directions are consistent with ECMWF winds (at ± 20°). Then the remaining ambiguities are resolved by an adapted PRESC...
متن کاملChange detection techniques for ERS-1 SAR data
Several techniques for detecting temporal changes in satellite synthetic aperture radar ( S A R ) imagery are compared using both theoretical predictions and spaceborne S A R data collected by the European first Remote Sensing Satellite, ERS1. In a first set of techniques, changes are detected based on differences in the magnitude of the signal intensity between two dates. Ratioing of the multi...
