Atmospheric propagation

1976
Questo capitolo, di un libro a cura di Alberto Sona, concerne la propagazione di radiazione ottica nell'atmosfera e il deterioramento della coerenza di un fascio laser. In una prima sezione ho introdotto le funzioni usate nella descrizione statistica di quantità fluttuanti, funzioni di correlazione, struttura e spettri e descritto la turbolenza ...

Sound Propagation in the Atmosphere

2007
Propagation of sound close to the ground outdoors involves geometric spreading, air absorption, interaction with the ground, barriers, vegetation and refraction associated with wind and temperature gradients. After a brief survey of historical aspects of the study of outdoor sound and its applications, this chapter details the physical principles ...

Instabilities of atmospheric laser propagation

SPIE Proceedings, 1990
The 'thermal blooming' nonlinearity associated with lasers' atmospheric propagation causes several other propagation instabilities which limit the maximum power transmissible by the atmosphere; these are stimulated thermal Rayleigh scattering, the closed-loop instability, the phase-compensation instability, and, in the case of a repetitively-pulsed ...

Ray propagation in oblate atmospheres

Icarus, 1976
Phinney and Anderson's (1968) exact theory for the inversion of radio-occultation data for planetary atmospheres breaks down seriously when applied to occultations by oblate atmospheres because of departures from Bouguer's law. It has been proposed that this breakdown can be overcome by transforming the theory to a local spherical symmetry which ...
