Drone Shield: A different take on gun defense

This is a concept I have been stewing on for a while and hadn't seen it discussed much as a potential solution or application for drone technology. It's very light on engineering, as I wanted to go for breadth and put as many options on the table before doing heavy analysis of the tech required and system constraints.

I welcome the feedback of this community - I'm new to avionics and much of the image recognition technologies I was extrapolating from existing applications.
