hb100 dopppler sensor max speed detection help

hello i want to ask if anyone used hb100 doppler sensor , can it detect speed 100km/h ? and if not is there any other doppler sensor to detect that speed , i want to do car radar speed

The pdf for that device gives this simplified formula:
fd = 19.49V (Velocity in km/hour).

Therefore 100km/h would be what frequency?
