Such echoes are typically returned from ground, sea, rain, animals / insects, chaff and atmospheric turbulences, and can cause serious performance issues with radar systems.
22.
While Comet ISON was the primary target, this mission also planned to observe other objects, including comet emission using BIRC and atmospheric turbulence using UVVis.
23.
Once combined, the findings should furnish researchers with an account of the roles played by chemical reactions, solar energy and atmospheric turbulence in ozone destruction.
24.
This is useful, for example, in free-space optical communications to compensate for atmospheric turbulence ( the phenomenon that gives rise to the twinkling of starlight ).
25.
A similar optical design can also be used in adaptive optics in astrophysics, in order to correct the aberrations caused by atmospheric turbulence in telescope images.
26.
The two most important variables affecting the degree of pollutant emission dispersion obtained are the height of the emission source point and the degree of atmospheric turbulence.
27.
Tiny pistons, or actuators, push or pull parts of that mirror, rapidly deforming it like a pair of twistable eyeglasses to compensate for each moment's atmospheric turbulence.
28.
In principle the transit technique can detect planets as small as Earth, though it cannot do so from the ground because atmospheric turbulence gets in the way.
29.
She and her colleagues then took a series of high-speed snapshots to freeze the blurring caused by atmospheric turbulence, and combined them into a single, sharp image.
30.
Eventually, however, this problem will be cured with the help of " adaptive optics " that automatically correct images within a telescope to compensate for atmospheric turbulence.
