Webtwo antennas that are spatially separated by a fixed distance either along or across the flight direction of the platform. Those INSAR systems are called along-track interferometric SAR (ATI) or cross-track interferometric SAR (XTI).

Dear all, There are basically three different concepts of SAR interferometry: 1) single-pass along-track interferometry, 2) single-pass across-track interferometry, and 3) repeat-pass interferometry. The single-pass concepts illuminate the surface simultaneously in time with two spatially separated ... Webalong the line connecting the radar and the object being imaged, often called the target or the scatterer.

WebFeb 25, 2024 · Since 2024, the number of civil and commercial SAR satellites in orbit has more than doubled. And at least a dozen more are set to launch this year, which would bring the total to more than 60.

As the sensor moves along the azimuth direction (along-track), the continuous strip of the ground area represented by the successive antenna footprints is called swath. The looking direction of the SAR antenna is called range direction.
