Quasi circular orbits around prolate bodies

open access: yesMonthly Notices of the Royal Astronomical Society, 2021
ABSTRACT Recent observations of stellar occultations have revealed rings of particles around non-planetary bodies of the Solar system. These bodies are irregular and can be modelled by ellipsoids. In the context of numerical integrations for the study of studying the region close to these ellipsoidal bodies, it is known that the use of ...

Circular relativistic motion of two identical bodies

Soviet Physics Journal (English Translation of Izvestiia Vysshykh Uchebnykh Zavedenii, Fizika), 1983
The circular relativistic motion of two bodies is discussed as the solution of previously obtained equations with a deviating argument in which the deviation of the argument itself is an unknown function of the time. In the case of circular motion the deviation of the argument does not depend on the time and is a root of a transcendental equation ...

Circular SAR experiment for human body imaging

2007 1st Asian and Pacific Conference on Synthetic Aperture Radar, 2007
In this paper, the CSAR (circular synthetic aperture radar) technique is introduced firstly. The principle of CSAR 3D (three dimensional) imaging and the spatial wavenumber support are analyzed and the 3D resolution is discussed secondly. Secondly, Ku band fully-polarimetric CSAR human body imaging experiments are performed, and the experimental data ...
