The V1 and FM-CW
In your earlier sticky regarding speed signs that employ radar, you state that these signs may employ an FM-CW modulation technique to sense the direction of vehicles in its field of view; whereby, this feature is used to isolate departing from oncoming traffic.
You further state that the V1 does not recognize FM-CW modulation as a valid police radar signal and tries to reject it. You go on to say that FM-CW is not allowed for police radar.
My question is that some police radar units have direction sensing capability i.e. the Stalker DSR [Direction Sensing Radar] and the Stalker II (in 2 flavors); SDR [Stationary Directional Radar] and MDR [Moving Directional Radar].
Can anyone please explain if the aforementioned radar units are now using FM-CW? If so, does the V1 then have to potential to not recognize what could be LEO (Law Enforcement Officer)?
Many Thank On Your Help With This Subject,
NO police radar uses FMCW, including the direction-sensing units like the Stalkers. These all use "CW" and use a different technique to sense direction: they can tell the direction of the target based on the frequency of the reflected doppler signal in relation to the transmitted signal.
Is it posible that some radars in EU work in FMCW?
I heard this somewhere,but can't remember
