Сonceptual design of small spacecraft with a high resolution P-VHF band bistatic SAR system

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2017
Spatial resolution is one of the most important characteristics of a radar image. Significant limitations in communication regulations should be taken into account concerning radar facilities in long-wave frequency ranges (P or VHF). These limitations do

Comparing C- and L-band SAR images for sea ice motion estimation [PDF]

The Cryosphere, 2015
Pairs of consecutive C-band synthetic-aperture radar (SAR) images are routinely used for sea ice motion estimation. The L-band radar has a fundamentally different character, as its longer wavelength penetrates deeper into sea ice.
