That's not how it works, the Patriot is a completely self-contained distributed system with a lot of redundancy. It has its own networked radars that can track both missile and aircraft threats. In the instance you are referring to, the Russians tried to flood the zone with a mixture of flight profiles simultaneously (ballistic, cruise, and drone) to overwhelm and complicate the defense. An air defense missile optimized for ballistic missiles won't be great for cruise missiles and vice versa. Patriot batteries contain different missiles optimized for aircraft/cruise missiles (PAC-2) and ballistic missiles (PAC-3).
While there are human operators, the Patriot has a fully autonomous mode that is turned on for large-scale attacks like most integrated defense systems produced by the US. When that mode is enabled humans are no longer in the loop; the networked computers engage all of the targets simultaneously, selecting the optimal weapon assignment and timing for each target. That was clearly used here. If the Patriot didn't have radar it wouldn't work and it clearly worked.
No Patriot system was damaged by Russian attacks, there is no evidence that anything got through. The only reported damage was an auxiliary system component getting hit by a large piece of falling debris, which was promptly repaired.
