You have just completed Chapter 2 - Satellites and Sensors. You can continue to Chapter 3 - Microwave Sensing or first browse the CCRS Web site for other articles related to platforms and sensors.
For instance, the Remote Sensing Glossary has platform and sensor categories that contain more information about various platforms and sensors and their use around the world. The glossary also has optical and radar categories of terms, to allow you to focus on these aspects of remote sensing technology.
If you are curious about detecting targets which are smaller than a pixel, see a detailed discussion in one of our "Images of Canada".
Until 1997, CCRS owned and operated a Convair 580 aircraft which carried a number of research instruments including a Synthetic Aperture Radar (SAR) sensor. There are a number of images from this instrument on our Web site, one of which is of the Confederation Bridge between PEI and New Brunswick taken while it was under construction.
