Webwhere, t 0 is offset in the azimuth direction that includes the drift in the spacecraft clock, and P R F is pulse repetition frequency that determines pixel spacing in the azimuth direction. Note that t 0 might have an influence on the satellite position, velocity information, and the geometric quality of a satellite SAR image.. For the pixel allocation in range direction, … WebBecause the thickness of the DCS can be ignored and the DCS can be compactly folded and completely deployed, its deploy/fold ratio can be defined as the ratio of the deployed area to the folded area, that is, ρ = S d / S f.Accordingly, based on the approximate circular ring shape of the planar origami pattern, its deployed area can be approximated as S d = …
