How capable was German naval radar during Operation Berlin?

What was German radar like at this stage of the war?

It was capable in its intended roles, but early radar hardware was highly specialized and could not perform every detection or fire-control task.

Radar performance does not support a simple good-or-bad judgment. Each set depended on the role for which its hardware had been designed, and changing roles required physical alterations rather than a later software adjustment. Operation Berlin itself showed useful detection performance even though radar could not solve every identification and fire-control problem. Specific sets and missions offer a better comparison than treating German radar as one uniform capability.
