toof Forums Junkie Location: Newcastle Registered: July 2003	Re: radar question Tue, 07 December 2004 08:37 in regards to how do the radar systems work out your speed... firsty n electromagnetic pulse is transmitted directed at the target. this travels at a roughly constant speed (constant enough for the accuracy that any road user is concerned about) this pulse hits your vehicle and is reflected by the solid surfaces of your car. this refelected component is detected by the gun which can then eaisly determine the distance between it and your vehichle. (C/time)/2 speed of light/time taken between send and recieve / 2 (round trip) this is then repeated momentarily after giving two distances and a time period between them. so the speed is determined by (distance A - Distance B)/time the time between the two pulses is generally a matter of milli seconds so your rate of acceleration is not going to effect the timing *that* much. i wouldnt plan of using the "your gun is inaccurate becasue i was accelerating" story on backing up your case. esp if your going to court.
