Precession Parameter Estimation of Warhead With Fins Based on Micro-Doppler Effect and Radar Network
IEEE Transactions on Aerospace and Electronic Systems, 2023Precession is a typical micromotion of a ballistic missile warhead in the middle of the trajectory. The modulation of the narrow-band radar echo by the precession warhead is mainly reflected in the micro-Doppler effect, which is manifested as the Doppler

Electronic spin transport and spin precession in single graphene layers at room temperature
Nature, 2007Electronic transport in single or a few layers of graphene is the subject of intense interest at present. The specific band structure of graphene, with its unique valley structure and Dirac neutrality point separating hole states from electron states ...

Precession Electron Diffraction
2012Precession electron diffraction (PED) is a key technique available to electron microscopists to elucidate the structure of inorganic crystals. A PED pattern is formed by the summation of a series of diffraction patterns whose incoming beam is tilted with respect to the optic axis.

The motion of a nucleus with an intrinsic multiple moment, in particular an intrinsic hexadecapole (16 poles) moment in external electrostatic multiple (triple) field gradients, is studied from a classical point of view. It is shown that in the classical approximation the angular-momentum vector of a nucleus with an intrinsic hexadecapole moment may ...

The geodetic precession as a 3D Schouten precession and a gravitational Thomas precession
Canadian Journal of Physics, 2014The Gravity Probe B (GP-B) experiment measured the geodetic precession due to parallel transport in a curved space–time metric, as predicted by de Sitter, Fokker, and Schiff. The Schiff treatment included Thomas precession and argued that it should be zero in a free fall orbit.

Inertial frames of reference and nonrotating frames of reference are discussed. Using geometric algebra as the principal mathematical tool, the Thomas precession of torque-free gyroscopes in special relativity is then derived in an exact fashion in two different ways. First, the equations of Fermi–Walker transport are employed to derive expressions for

Simulations of Precessing Jets
2003We report on the results of a three-dimensional, relativistic, hydrodynamical simulation of a precessing jet through which a compact blob of matter is set to propagate. We conclude that the morphology of superluminal sources is the result of a complex combination of phase motions, viewing angle selection effects, and non-linear interactions between ...
