Sentinel-1A radar image of Montréal
A Sentinel-1A SAR image of Montréal, with the two DLR precision transponders. The first test overflights with Sentinel-1 were performed after successful installation and commissioning of the transponders on and close to the CSA complex. The transponders appear as bright crosshairs and are easily distinguishable from the image background. Known as impulse responses, they are shown again in an enlarged form in the box at the bottom right. The reflection from the CSA building is clearly visible in the vicinity of the lower impulse response.
