Not correct. In the mid 60s, the BQQ-5 series and the BQQ-6 were both developed, both of which had spherical arrays. Early versions of the Q-5 did use a system like you described for it's analog trackers, though it's digital ones were done purely by the system itself. Regardless, both of these systems (or their immediate predecessors, where the tech was developed) were deployed in time for the time frames of this game, and both have decent D/E (depression/elevation) coverage in addition to the 360 degree azimuthal coverage.
