Oh boy…that could be a problem for the Embassy compound if the drones can fly under C-RAM’s radar. As if they should be stuck on that compound in that low grade war zone in the first place.
Counter battery systems weren’t really built/engineered for this mission. They work really well for the core mission, as you likely know, enabling counter-battery fire missions reportedly before the bad guys fire their second round. Those CRAM systems (like Iron Dome) intend to kill inbound munitions on impact or proximity detonation kill. (again, not news to you.)
The planar antennae are capable of the mission *IF* the UAV is at altitude, similar to a mortar shell,rocket, or artillery round (unlikely from Hamas) but the software and the RF has to be tweaked ($$$) to get targeting data to the systems that kill the targets. Also ROE for UAVs often require visual ID/confirmation, so ... ya don’t need that for incoming ballistic projectiles - they ARE foe. Point being US forces are fielding new weapons systems ($$$$) to combat what we call ‘drones.’
P.S. Search on Iron Beam and Davids Sling - cool stuff from the Israelis of course.
