If you count nothing but the earliest version of military radars, then of course nothing but the military has funded it. I will, however, not count pulsing as more than an improvement to the basic invention of distant object detection with radio waves.

Taking a system from prototype to mass produced, worthy as this investment might be, is not inventing it.
