This does remind me of my first job out of college way back in the radar and microwave department of a large military contractor designing thick & thin film modules for the navy.
One of the radar modules was installed in a CIWS (Close In Weapons System) similar to what the video shows -- however the CIWS was meant to be the last resort for taking down missiles about to hit the ship.
The navy complained the radar module was out of compliance with the contractual requirements for detecting and tracking small objects including both metallic & non-metallic objects -- which are the equivalent of the profile of missiles coming in at various angles which may has various coatings on missiles to reduce their radar signature. Their most important complaint was about non-metallic objects.
The radar department engineers did a lot of work and some updates were made. I was the junior engineer responsible for testing the module.
I was part of the group that went to the navy test firing range. It was right on the beach with a CIWS mounted on the shoreline firing over the water. Other equipment was arranged to throw objects across the range -- similar to skeet shooting. Plus some small drones which flown across the range via remote control.
There is a whole crowd of navy brass and corporate executives -- plus our small team of engineers plus some navy enlisted guys doing the set-up and work.
We power up the CIWS system with the new module and the first thing that happens is a large seabird flies across the range. Surprising everyone --the CIWS quickly whirls into action after detecting the bird -- and shortly thereafter the only thing we see is a few feathers floating down.
The top navy officer comments, "We see the non-metallic object problem is gone".
The new module went on to pass all the tests.
