Consider that in a microwave oven, radio waves are converted into heat. This results in reemission of the energy, but at a different frequency than the absorbed energy. Radar is based upon energy reflected at the *same* frequency it was transmitted at, but Doppler shifted. Regards, Robin van Spaandonk http://users.bigpond.net.au/rvanspaa/ Competition provides the motivation, Cooperation provides the means.
