Exploring new applications of elliptic functions to image encoding, developmental biology. Approaches are quantitative and numerical, based on classic complex functions that realise double periodicity. Possible image compression techniques will be explored.
Invented the geometry of space borne SAR for the MDA Digital Seasat SAR processor in 1977. The theory provided critical inputs to the processor such as the azimuth fm rate and was for compressing the signal to zero Doppler; as well as defining all the coordinate systems required and the transformations between them; and the transformation of the image to the chosen map projection. The project was recognised as an IEEE Milestone in Electrical Engineering and Computing on 9 October, 2014. The first digital image incorporating this new geometry and the team's advanced signal processing was produced in November 1978 and depicts the area around Trois-Rivierès, Quebec. The target wharf position deviation was determined to be +250m along track, ~50m across track relative to the official EMR 1:50,000 map. The orbital data was supplied on the data provided to MDA by NASA.
