mmWave is the usual solution for this; I know that Amazon were at least testing using mmWave but I'm not sure if it made it to their production drones.

  Would that act like radar in mmWave? Send out pulses and see where they come back and time difference to estimate range?

    Yep. See eg the TI AWR1843 and related AWR parts.
