There are three main components of system noise, namely antenna noise, receiver noise and sky noise
. The sky noise
component is out of our control but the other two can be influenced by design.
Local interference and sky noise
is also less on these bands, several of which are protected from military and civilian transmissions by U.S.
The band, who have supported rock giants including the Deftones, My Chemical Romance and Coheed and Cambria, are headlining Leeds venue The Cockpit to support the UK release of their album Blue Sky Noise
''I was like, dude, you are going to choke to death on stage - but I never asked him to stop because I was almost sure that would increase record sales!'' The band, complete with crisp-eating vocalist, play Birmingham's O2 Academy tomorrow, ahead of the release of new album Blue Sky Noise on July 26.
With Blue Sky Noise the band have tried to ring the changes.
Their visit to these shores comes on the back of massive success for the band in the States for their new album Blue Sky Noise.
Produced by Grammy Award winner David Bottrill (Tool, Muse), Blue Sky Noise was released to critical acclaim in the US last month.
The scriptwriting process for the short film, Sky Noise
Polaroids (Jean Poole, 2003), made excellent use of online connectivity--it was simultaneously written and shot by over a dozen film groups worldwide who responded to a call for participation distributed on email lists.
[T.sub.sky] = total sky noise
temperature ([T.sub.sky] = [T.sub.cos] + [T.sub.sun] + [T.sub.atm] + [T.sub.man])
Variations in the reflectivity of natural terrain materials, and metallic objects in particular, generate a difference temperature image relative to the background terrain temperature by virtue of the reflection of sky noise
This is analogous to aperture photometry where, for a faint target, the best S/N is obtained with a small photometric aperture which only includes a fraction of the light of the target (inclusion of the outer pixels is detrimental rather than useful, since the stellar light is lost in a sea of background sky noise
The contrast temperature between a metallic object and the terrain background is due to the reflection of sky noise
from the metallic surface.
