The shot noise of ‎the signal is calculated from the multiplication of signal voltage to noise scale factor. The noise scale factor is ‎estimated from the linear relation between variance and mean of the background noise. ‎The SNR of 150 and ‎‎1500 temporal averaged signals is equaled to10 at a height of 4 and 6 km respectively.‎ CP - IRAN IN - LG - eng PB - opsi PG - 1497 PT - Research YR - 2015
