AL Priority - What Have I Been Hit By?

[Mirage]

LOL... I am sure yours will see some more action but my unit has a big head start.

I have a feeling you'll keep the lead on this one, but I must say you sure were testing that Stalker.

I can't wait to test some more.

I do notice I also have 9 Poliscan's listed so one of the guns is coded to the wrong name and we will have to get that fixed.

It's the LTI LR-100. I just shot it again and the Poliscan value increased to 13.

Have no doubt we will get this fixed Monday.

Sometimes with my laser tester set for Ultralyte (100pps), if I shot my Blinder HP-905 a few times with it, it would eventually announce 'Vitronic Poliscan'

Vitronic PoliscanSpeed = 100 pps.

Probably explains why youre getting IPT on the 100pps UltraLyte if its responding with the Poliscan algo.

I'm not sure the Poliscan is 100pps or the AL would have had no issue with the LR-100. I'm no expert on the poliscan, but I think it's VPR regardless since it's not used in my area I am going to disable it and test this morning against the LR-100 to see if your assumption is correct. It would make sense if the AL was detecting poliscan and sending the wrong jamming signal that we would get IPT. I am confident that AL will have this all worked out tomorrow and I'm glad we were able to help them make the device that much better. I'll let you guys know what I find.

Excellent observation on your part,wb !
Could very well be the culprit.

Here's the data from the manual ;

9.2 LIDAR
Range of measured distances 10 m – 75 m
Measuring frequency 100 Hz
Number of measurements/scans 158
Angular resolution (horizontal) 0.28 °
Horizontal measurement angle 45 °
Horizontal beam spread 6 mrad
Vertical beam spread 19 mrad
Depth resolution 312.5 mm
Pulse duration 15 ns
Pulse width 4.5 m
Resolution A/D-converter 8 bit
Power supply 12 V DC
Laser class 1

We used to think it was VPR, as some YouTube vids with Whistler RD's which display pulse rates, used to show it shifting between about 65 - 100pps over a few seconds.

The reality is that as the lidar beam scans across the road, the RD picks this up as a change in pulse rate.

After testing again today it appears if you disable the poliscan it will also disable the alerts for LR-100. So it looks like AL will need to take a look at the two and correctly identify which one is being used as apparently they have different jamming algos even though they are 100pps each.

Oh,so it's not an oscillating back-and-forth sweep then.Sounds more like a multifaceted,rotating mirror it would seem to be.

I'm told there's a rotating prism type thing in there

Here's some blurb from our local police force ;

The PoliScanspeed camera is designed to concurrently detect, track and enforce multiple
vehicles on single lane and multi-lane roads. It uses 3D scene capture and vehicle tracking
to determine the speed of each vehicle and whether the vehicle is exceeding the set speed
limit.

The PoliScanspeed camera uses a high resolution scanning laser, constantly capturing the
scene within the measurement zone. This enables individual vehicles to be detected and
precisely tracked through the measurement zone.

Our LEO's also use the 100pps Ultralyte's so will take it easy for a a bit. Hopefully the ALP is not trying to use the UL100 algo against the Poliscan
