I would like to throw a neat idea out there for an interesting RD testing procedure. As we all know GOL uses Eccosorb radar absorbing foam to greatly attenuate the signal intensities from radar guns so that they can then perform straight-line RD sensitivity tests. These straight-line sensitivity tests simply show the relative detection ranges of the radar detectors versus a given radar band or a given radar gun frequency within a radar band. I know, a lot of people don't trust the foam. But if you read the engineering docs on Eccosorb's web site, you will see that the foam merely attenuates (absorbs) radar and otherwise does not affect the radar signal in any other way with regards to polarization, wave front errors, et cetera.
Anyway, the question keeps coming up as to what the ramp-up profiles are like on individual radar detector models. This year's SML test results featured indicated signal strengths vs. maximum signal strength for radar detectors being tested at various distances from the radar guns. Carl Fors mistakenly assumed that radar detectors have linear ramp-up profiles in relation to distance from the radar gun source. We all know that this is not the case with several radar detector models.
So, I propose a straightforward test setup as follows:
1. A 40 foot long wood plank supported by sawhorses. Wood, due to moisture trapped inside of it, inherently absorbs any grazing or direct radar beams for that matter.
2. 12 volt battery and long yet appropriately modified power cords with 18 gauge power and ground wires to provide power to the radar detectors being tested.
3. Radar gun at one end of the plank, attenuated by foam on all sides plus whatever amount of additional foam is necessary in front of the radar gun such that the most sensitive RD just detects the radar gun near the opposite end of the 30 foot long wood plank.
4. A tape measure attached to the side of the wood plank to indicate distance from the radar gun end of the plank.
5. Thus each radar detector can not only be easily tested for its straight-line sensitivity, but also each radar detector can then be easily and progressively moved along the top of the wood plank to then test its indicated signal strength versus distance from the radar gun source.
The test data can then be computed not only into dBm sensitivity numbers based on on reference RD whose dBm sensitivity numbers are known, but also can be converted into graphs to show the actual ramp-up profile of each radar detector model based on distance from a radar source.
Well, what do you guys think?
