If you need a 100 meter antenna - could one be approximated using multiple drones in a coordinated 100 meter parabolic trajectory?

Yes, if you can coordinate and hold their position to ~1/10th of the wavelength (gets challenging above a few GHz), and synchronize their transmitters/receivers with ps accuracy (feasible if there's no GPS interference). And somehow you're exchanging the raw signal components amongst all the platforms.

The parabolic distribution is not at all needed in this case, you would just adjust the phase at each unit based on the distribution you have.

It is a thing that's considered, mostly for very low frequencies (1-100MHz) where all the above challenges are vastly simplified, and also large antennas (potentially km) are needed for any kind of directionality.

No need to hold their position that accurately, just need to know, ideally in real-time.

Does UWB provide enough accuracy to be useful or would you need something else?
