| Abstract |
One way that ERS satellites (the European Space Agency's European Remote Sensing satellites) remotely sense the Earth is by sending out C-Band (5.66 cm wavelength) radar pulses and observing how those signals interact with various objects on the ground. This remote sensing method has some major advantages. For example the transmission of radar signals in effect provides "lighting" for the sensor; the antenna senses the radar backscattered from signals which it sent out, and therefore is not dependent on sunlit conditions ("it can work day or night"). Another advantage stems from the radar signals' characteristic of passing relatively unaffected through cloud cover, providing the ERS AMI-SAR (Active Microwave Instrumentation, Synthetic Aperture Radar mode) with the ability to image a region regardless of weather conditions. These advantages are magnified in the polar region, where the long winter nights and stormy seas have hindered other sensors' efforts to provide continuous coverage.
