Engineering Physics Annotation << Back The pulse characteristics of the traces «Earth – Space» in the near IR region of optical spectrum V.P. Busigin, N.G. Busigina, Yu.P. Vagin If the signal’s rise time in the source is that appreciably significance hase a fricvences comparable with the value of ? c, where the ? is the scattering coefficient, and the c is the signals velocity, than the source is considered as unulse characteristic is the response to the ?-pulse. The deduction about of the extent the signal’s distortions may be done, if there are the signal models and the trace pulse characteristics. In this paper the pulse characteristics of the atmospheric traces is presented for the optical radiation go into Kosmos fran isotropie source. The analisy is made for pulse characteristics depending on sky state and the surface of the Earth. Key words: Signal, trace, pulse characteristics.
