I looked at the results posted at http://www.guysoflidar.com/testjan06.html . Am I correct in thinking that the numbers shown are the number of feet before the radar source?
Assuming that's correct, another variable that I would find interesting is "Seconds to Radar Source @ xx MPH after First Detection." One can then compare the time that the RD is buying you.
Even better.... how close does one have to be to these various radar guns to be locked and clocked? Is it a shorter distance than the detected range? If so, it would be good to see the amount of time between first detection and when the the Enterprise's phasers had a lock on you, so to speak. This variable might be "Seconds to Lock (i.e. destruction)." This is the real metric of value.
Additionally, it wouldn't hurt to replicate the each test scenario more than once. (e.g. Using V1 on Ka 33.5 drive up and take measurements three times, perhaps varying the conditions). Perhaps you did that. I dunno. My guess is that the readings will vary from test to test. In that you could get an average response for each test situation.
Also, what was the difference between your test and the infamous, was it 1992, Car and Driver test that V1 always relies on?
