if you did it why fight it?
Dont try to fight. you will just piss off the judge. appear to court and plead Guilty and they will give you a better break then no contest or not guilty. Judges appreciate honesty.
Also i dont know what the heck the cosine effect is. Maybe you are thinking of an ionispheric bounce. also plead guilty and question the officers certification in radar. only about 10% OF Police Officers are radar certified and if they are not it has a good chance of being dropped.
Edit: Not anything to you Dampachi, but isnt there a traffic violation forum? you see tickets posted in here all the time and then you see threads locked for being in the wrong spot.
