The RADAR we see in Roswell (1947 radars) is a simple wave radar, in high frecuecies to detect objects and marc it`s position, but it can`t determinate direction or speed (that ability come later with the Doppler RADAR that can determinate direction,speed and acelerations parameters), is the same type of radiation, waves, but microwaves make vibrate the H2O molecles of the food to heat it (i guess), radar just use the wave ping on certain surfaces (radar waves has a little efect on perfect plane surfaces, see F-117 stealh).
Also, Nuclear explosions products a wide range of waves , from ALPHA, BETA (the dangerous ones), GAMMA, etc...
Please, if i had made a mistake (very possible, because all of this i readed a long time ago) correct me!
Lot's of good info from Javier here - thanks.
Technically, the professor was correct (the best kind of correct) - it was a radar dish in "Roswell that Ends Well" (there was no microwave communication in 1947). Leela was not far off, however. In the early days of radar and microwave cooking, the words "Radar" and "Microwave" were used pretty interchangably. Consider that one of the very first microwave ovens was marketed under the name "Ammana Radar Range" (Range = Oven)
