Student research highlight staggered synthetic aperture radar

Synthetic aperture radar (SAR) is an active microwave remote sensing technique that can provide high-resolution images independent of sunlight illumination. Moreover, because clouds, fog, and precipitation do not have a signifcant effect on microwaves, all-weather imaging is possible. Because of the coherent reception of the radar echoes, an effective long “synthetic” antenna can be generated by signal processing and exploited to achieve high resolution in the fight (or azimuth) direction. These peculiarities make SAR attractive for the systematic observation of dynamic processes on Earth´s surface [1].
