If not, have u actually seen/touched an air-borne radar?
Have u ever operated a radar?
(It's more common that U think, ever heard of police radar gun,eh?)
Do u even understand semi-layman articles on radars, appeared on, if any, say, scientific america?
If not, pls STFU
I only have courses on electrodynamics, quantum mechanics, optics and basic electronics, just the basic theory side, so I refrained from BSing on radars like u did
