slide 7

SAR Satellites use a right-side-looking radar system, where the sensor is tilted from the needle direction. The radar beam is also tilted, and the angle between the needle direction and the radar beam is called the look angle. The video demonstrates how SAR observes the Earth, and the episode represents the footprint of the radar beam. SAR Satellites is a right-side-looking radar system. The term side-looking means the sensor is tilted from the needle direction. The red figure shows the basic geometry of the side-looking radar system. The radar beam is tilted from the needle direction. The angle between the needle direction and the radar beam is called the look angle. I will talk about the geometry in more details later. The video shows how the SAR observes the Earth. The episode is the footprint of the radar beam.
