Re: 121 km/h in a posted 80 km/h - Disclosure attached
There is more panning than you realize as target is moving rapidly and has to stay in middle of cross hairs. Also as I stated there is no stand, right? That means there is handshake. Then you have the problem of beam width and 1.8m radius around car that lidar is all the time measuring at 300m. The ...

Re: 121 km/h in a posted 80 km/h - Disclosure attached
People are getting hung over the term least squares. All you need to know is that an average doesn't guard against outlier results and is affected by them. The lidar algorithm doesn't discard sweep error results. It discards outlier results. If there is too much sweep the sweeping results might not ...

Re: 121 km/h in a posted 80 km/h - Disclosure attached
You stated the average of least squares will guard against sweep error. I would like you to expand on the theory that you learned in training. You can dumb it down anyway you like. If you have 2 sweep error readings and 3 "good" ones how will the average of least squares guard against the ...

Re: 121 km/h in a posted 80 km/h - Disclosure attached
Can you expand on the average of least squares will guard against sweep error? Is that your personal theory?
What will happen to the lidar algorithm if the sweep error is bad enough?
Do you know why FOV is important here?

What is the Field of vision at 8x magnification? Can you answer that question or not?
There will be sweep error.
There will be sweep error.

Re: 121 km/h in a posted 80 km/h - Disclosure attached
I meant to write including objects in reading @ 2X width of beam. Really not sure how calculation was made or if it was taken but he really can't say what he could've hit in a 0.9 m radius circle 300 meters away in the dark. Yeah if it contradicts distance reading you go to town on his training. Can...

Re: 121 km/h in a posted 80 km/h - Disclosure attached
The purpose of having a standardized template for the officer's notes which has beam width specified is so the officer will document what the beam width is at the distance of the lidar reading. The officer is not putting the beam width of the lidar gun at 300 meters there. The reading was taken at a...

Re: 121 km/h in a posted 80 km/h - Disclosure attached
The officer wrote in his notes the beam width was 0.9m. It changes over distance. So the officer had to be approximately 300 meters away when he obtained the reading. If the beam width is 0.9m that means officer can miss the plate by that much and still theoretically get laser beams back from hittin...

Re: 121 km/h in a posted 80 km/h - Disclosure attached
The officer was approximately 300 meters away based on my calculations using beam width of .9m and lidar gun specs. What was volume of traffic? Obviously it was dark but was it raining ( I can't make out the RDS conditions)? Basically the officer is stating he is sure he wasn't off by 0.9m at a dist...

Re: Speeding and Follow Too Closely
I believe the officer has to record his notes no later than one week after the incident. His notes are basically the disclosure you will be given. Ask officer when he wrote his notes and prosecutor reason for delay. There really shouldn't have been a delay there.

Re: Speeding and Follow Too Closely
In reality Argyll, as it relates to bias, we are both very biased. However, I am upfront about mine. I don't wish personal harm to befall officers but I don't wish them a nice day or a peaceful life so that I can look objective or to irritate them whatever the case may be. Once again you bestow upo...

Re: Speeding and Follow Too Closely
I'm giving good advice. To adequately prepare for a trial one should realize what they are up against. Even if you look on this website most people that have radar gun equipment logos or are former police officers arent sympathetic to your viewpoint. No matter the situation they deep down want you t...

Re: Speeding and Follow Too Closely
Zatota, The first appeal I had I lost. I proved mathematically that the officer's observations severely contradicted the radar gun reading. The judge took over 3 hours to deliberate but stated the reason I lost was because I didn't take the stand to declare my innocence. I stated math is the ultimat...
