How to expand range of Doppler Sensor(HB100 breakout)

TomGeorge:
What is "CAN Satellite."?

I'm guessing this: ESA - What is a CanSat?

Ignoring the range problem, I would think doing Doppler motion detection from a moving platform without rather more sophisticated platform navigation and radar sensor is a non-starter. Also, it's unlikely the rules would allow launch if there were other airborne objects in the vicinity.

Very cool platform though.
