Un autre domaine essentiel d’application de la notion de diffusion réside dans la propagation dans toutes les directions d’un rayonnement initialement unidirectionnel, sans perte de l'énergie qu'il transporte, après qu'il a pénétré dans un milieu pouvant être considéré comme constitué de particules avec lesquelles il interagit. Ce phénomène de rayonnement diffus s’applique tout particulièrement aux rayonnements électromagnétiques, parmi lesquels figurent le rayonnement solaire ainsi que les rayonnements infrarouges émis par la surface et l'atmosphère terrestres. Dans ce cas, un rayon de lumière traversant l'atmosphère subit généralement une multiplicité de diffusions successives. Lors de chacune d’entre elles, il peut soit continuer son trajet dans une direction assez proche de celle qu'il maintenait(c'est la diffusion vers l'avant), soit être repoussé dans une direction plus ou moins proche de celle d’où il venait(c'est la diffusion vers l'arrière ou rétrodiffusion) [...]  4, record 14, French, - diffusion%20vers%20l%26rsquo%3Bavant

Lock-in is a fundamental physical phenomenon associated with all oscillating devices.

Record number: 34, Textual support number: 1 CONT

Pulse Compression. In collecting the SAR data, a long-duration linear FM [frequency modulation] pulse is transmitted. This allows the pulse energy to be transmitted with a lower peak power. The linear FM pulse has the property that, when filtered with a matched filter, the result is a narrow pulse in which all the pulse energy has been collected to the peak value. Thus, when a matched filter is applied to the received echo, it is as if a narrow pulse were transmitted, with its corresponding range resolution and signal-to-noise ratio.  3, record 34, English, - pulse%20compression

Traitement en distance [-] compression d’impulsion. Pour obtenir une résolution en distance satisfaisante(de l'ordre de quelques mètres) il est nécessaire que l'impulsion ait une durée d’émission très brève(quelques nano-secondes).

NRCS-40 is the value of this regression line at an incidence angle of 40°.

Multi-scale composite models based on the Bragg theory are widely used to study the normalized radar cross-section (NRCS) over the sea surface. However, these models are not able to reproduce correctly the NRCS in all configurations and wind-wave conditions. We have developed a physical model that takes into account, not only the Bragg mechanism, but also the non-Bragg scattering mechanism associated with wave breaking. ... Models of the normalized radar cross-section of the sea-surface (NRCS) at intermediate incidence angles are usually treated as a composite models describing the combined effects of Bragg scattering mechanism (effective for surface ocean waves whose wavelengths are of the order of the electromagnetic wave) and local-titling effects due to longer underlying waves (Plant, 1986, Donelan and Pierson, 1987, Romeiser et al., 1994, Romeiser et Alpers, 1997, Janssen et al., 1998).  3, record 46, English, - Bragg%20scattering%20mechanism
