Spaceborne laser radar.
Flom T. Flom T. Appl Opt. 1972 Feb 1;11(2):291-9. doi: 10.1364/AO.11.000291. Appl Opt. 1972. PMID: 20111497
This paper describes a scan technique whereby a narrow laser beam is synchronously scanned with an equally narrow receiver field-of-view without the aid of mechanical gimbals. Equations are developed in order to examine the maximum acquisition and tracking rates, and the m …

Feasibility of Replacing the Range Doppler Equation of Spaceborne Synthetic Aperture Radar Considering Atmospheric Propagation Delay with a Rational Polynomial Coefficient Model.
Hou S, Huang Y, Zhang G, Zhao R, Jia P. Hou S, et al. Sensors (Basel). 2020 Jan 19;20(2):553. doi: 10.3390/s20020553. Sensors (Basel). 2020. PMID: 31963915 Free PMC article.
Usually, the rational polynomial coefficient (RPC) model of spaceborne synthetic aperture radar (SAR) is fitted by the original range Doppler (RD) model. However, the radar signal is affected by two-way atmospheric delay, which causes measurement error in the slant …
