Hi
I need an estimated equation for calculate Atmospheric Absorption Loss (dependent on range and frequency and elevation angle)
thank you very much

atmospheric loss equation

Hi,
if u want know the equation for atmospheric absorption loss refers to "Radar HandBook" second Edition by Merrill Skolink.
Go to section 2.7 and see the topic procedure for finding the range dependent loss equation.

U can seein Radar design and principles by Nathnson.
Or
Weather radar applications by G.Collier.
Weather Radar by Zrnic and Doviac.
If u r not find still, u just message to me i will try to send the scanned of those pages.
