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
