Next thing we know, flares the size of pringles cans started bouncing every which way, as if the bomber shat out the 4th circle of hell.
Sounds like a modification of a
story in Snopes, what about these technical items:
Additionally, there are different types of scan profiles in use, such as circular, unidirectional, bi-directional, helical, raster, palmer, conical, and track-while-scan. Police radar units are directional ones that send pulses in a relatively narrow cone in the direction the officer points the device. (This type of radar is used to prevent the operators from being exposed to the devices' high-frequency radiation over long periods of time.) Therefore, it's pretty unlikely that an officer pointing a hand-held unit at an incoming car would also manage to illuminate a flying aircraft — an intervening hill, a large building, or even heavy plant growth would block any stray signal.
Surface-to-air missile (SAM) radars behave differently than handheld police units. Also, each type or model of radar gives off very specific characteristics, and the onboard systems in military planes can differentiate among these types of threats (e.g., a SAM-2 vs. a ZSU vs. an F-16). To quote from Info-Strategies’ web site, "Every radar produces a radio frequency (RF) signal with specific characteristics that differentiate it from all other signals and define its capabilities and limitations." Excepting a case of incredible coincidence, the police radar wouldn't be on the "threat" list. Also, SAM radar units are also relatively short range systems (30-50km), since the usual practice is to employ longer-range tracking stations to keep watch on incoming aircraft, then alert the SAM unit in the aircraft’s flight path of the impending arrival of the hostile plane.
I doubt a police radar unit would cause firing of flares from a parked aircraft as the flares and defensive systems shouldn't have been enabled while parked.
