Current interferometry results in Canada

A number of groups are currently active in radar interferometry in Canada, including government institutions, universities and industry. This paper will present a survey of interferometry applications in Canada, and illustrate recent results. In the airborne radar domain, early research with the Canada Centre for Remote Sensing (CCRS) Convair-580, has led to successful commercial programs at MacDonald Dettwiler (MDA) and Intermap Technologies. MDA has built three single-pass interferometers that are in operational use in the Amazon basin, and Intermap have built five systems that are producing DEMs with 1-m vertical accuracy. On the satellite front, RADARSAT-1 data has been used for repeat pass mapping in the Canadian Arctic. A number of subsidence and landslide sites are being continually monitored with the permanent scatterers technique. A 3-satellite constellation, the RADARSAT constellation mission, will support future InSAR applications.
