Anyone has technical recommendations for a low--cost (24GHz+) radar sensor that can be incorporated into a device that measures the velocity of a single small metal object?
Here are the parameters:
- single small solid metal object, such as lead pellets/balls, between 4.5mm to 8.5mm diameter
- distance envelope of object from radar sensor: 12cm-2m traveling away from sensor at zero angle
-velocity: minimum: 200 km/h - 1300 km/h (prefer 200-km/h to 4800 km/h) /200 fps-1110 fps or 200 fps - 4500 fps/
What would be the detection-zone of such radar in front of the sensor for such a small object? For example: the radar can measure a 4.5mm diameter object from 25cm-65cm (that would be a 40cm long detection-zone) in front of the sensor.
