As rk hinted on: the only possible way (at this moment) would be a digital, cataloged database of frequencies, cross referenced to their relative signal strength, or inherent attributes (certain radar emmiters, such as those using the mls-4890-U klystron (and some using magnatrons, as well) leave a signal "scar", and that would leave the ability to determine exactly what emitted the signal.
Processes such as current ramping, or sine signal analysis could properly determine the originating system. and then the altitude, distance, speed, frequency, and course. However, with those capabilities, you are no longer looking at a dash mounted radar detector, you are looking at a full-fledged radar system. (need further info, check out some of the USN Air/Surface Search radar models, such as the SPS-49, SPS-55, SPS-67, SPS-73, or even the older Italian RTN10X.) You'll see, in any of those, there is not only a large amount of power required, there is also a substantially larger amount of storage room, compared to your windshield, and a MUCH heftier price tag (x,xxx,xxx.00)
So, RK.. the ability to determine the originator, SOLELY on the signal frequency (a door at 24.150 or a cop at 24.150)could be determined, because the square would have certain scar marks (peaks, pivots, ramps, slides, etc, on the pulse, which would be caused by the radar oven, or crystal itself. (now... how noticeable is a cop car's scar, compared to almost a million watts of output on the surface search, I wouldn't begin to think it would be.. but it can be done.. lol)
And Kremit,
The ability to do so, even though it DOES exist, is not feasible, as I stated before. The "technology" that the radar makers are using is not "new"... it isn't secret, and it isn't there.. The bottom line is this:
the more features you want, and the better you want it, the bigger, hotter, heavier, or more expensive its gonna get. You HAVE to have one of those! (if not more than one...) So.. you COULD effectively weed out MOST false signals, however, there ARE still going to be other systems that use the same frequency as a radar gun,and it WON'T filter that, unless it is a pretty functional system, and that costs money (see above figure on radars...) on another note.. there ARE shifts in frequencies that will change a signal, however not deviate from the center of 24.150. Its called bandwidth, and it can vary .01 to .25 or greater, depending on what application you talking about. (think back to what was referred to as "side band" on CB's and HAM radios.
End point: RK is right: selectivity, and sensitivity are the two most crucial components in a radar detectors abillity to perform to specification, or above
Krem is right: signal isolation and identification is a possibility, and may become a more useable feature in the future, just not now...
Now back to your regularly scheduled thread.
