Actually I have a clarification. There will be 2 drones. One is for intelligence, it will have a camera with 4K/30FPS at least (the bigger - the better). It will fly like 10-20 km away from the protected target in order to recognize the shells and the rockets. It just captures the video and sends information to some server being located near the protected target. This server processes the data from this drone, recognizes shell or rocket, calculates its trajectory and sends few simple "homemade" drones with 500g of explosion to the calculated trajectory of that shell/rocket. So it will not try to detonate 1 meter near the rocket, but just catch the rocket directly and detonate because of the contact with the shell. We can calculate the trajectory with some error of course thus there will be 5-10 such drones located in chess order to cover few meters in radius along the trajectory.
