A web application with visual SAR processor for education

In this paper, a web application with a visual SAR processor is proposed in consideration of educational use and computer system environment. A system structure of the web application employs Ajax technology and object oriented software components. The main window of a client computer consists of view area, scene selection tab, tool panel, vertical and horizontal scroll bars. The processor can generate intermediate complex and map-projected images from raw SAR data using the range-Doppler method. An example of the educational use is demonstrated by compositing orthorectified images generated from a pair of ALOS PALSAR data observed by ascending and descending orbits.
