Detecting Ka.... GOL Test

[ES13Raven]

Thanks to the GOL, we now have another question answered...

Ka 35.5 GHz is the hardest Ka to detect (Kustom, Decatur)

Ka 33.8 GHz is the 2nd hardest to detect (MPH)

Ka 34.7 GHz is the easiest Ka to detect (Stalker)

Good job guys

I seem to have the most trouble detecting the Stalker ATR when the NY troopers are using sharp angles

That was the case with these particular radar units, but might not necessarily always be the case. Here's the specifications for the output power of the units we used:

Enforcer
12-30 mW nominal
50 mW Maximum

Stalker
10 mW minimum
25 mW nominal
50 mW maximum

Talon
15 mW typical
25 mW maximum

So in general, the Talon has less output power than the other two units that we used. I am sure antenna design plays a big role as well.

Well said. To begin with I would not say my great 985 has anything on these newer units, but I recieved a confirmed blip of Ka 35.5 over one mile away, then again it was in a area full of building. So case in point, for LOS we can expect great range, it is these angles that causes trouble for us. Each detector performs deferently in different situations, further proof that not one detector can provide full proof perfect performance maximum range all the time. That being said, top 3, top 4, whatever, but you buy the best you get the best.

Yeah that is a good point, everything really depends on (each certain) circumstance.

Jim, what was the distance that the radar guns actually read the speed of the cars? In other words, how many seconds after an alert would you have before your speed was registered in your setup at GOL?

Wow, that is some serious power output vs our Multanovas 0,5mW to 0,2mW!...

We never noted that or even paid attention. Maybe on the next test we can do this. All this test was about was PURE perfromance

Happy, how many runs were done on each detecor/gun? Did you do multiple then average them, or only one per gun due to time constraints?

Basically only one run each detector. Of course we would start the run over if any other vehicles entered the test course etc etc.

If we did multiple runs, we would publish all of the results and let you guys do the averaging :wink:
