When was the last time, you measured Water Adsorption at 10Ghz? Obviously, not in the last 50 years, since Xband has come into Marine Radar use. Water Adsoption is a Significant cause of loss of Targets, when the humidity of the air between the transmitter Perhaps you mean 'absorption?' 'Adsorption is hardly possible for rf. and target is high. 4Kw PPP wil certainly "Burn thru" more humid air than 2Kw PPP. One must also consider, that heavy rain, like in squalls, will also tend to drop the siganl level of received targets in the Xband, due to defraction of the RF by the rain droplets. These, and other KNOWN, physical elements all play a part in Maximum Detection Distance of a target in Marine Radar Systems. Me one who deals with this stuff every day......
