User talk:Filmacu/Watson radar power conjecture

Usefulness of this article
Hi,

In the radar article, all the components of the range of a radar, any radar, are well explained :
 * The non-ambigous range of a radar depends on the Pulse Repetition Rate.
 * The amplitude of the signal has to do with the level of the return signal. This signal has it has to go to the target, which reflect only a fraction back to the source, and there is attenuation through air and precipitations both ways. If the original signal is weak, the return might be too low to be noticed by the electronic of the receiver which will limit the range.
 * Finally the radar beam rises about the Earth due to its curvature.

Ther is nothing conjectural, so this article you are writing is redundant.
