It will take some time 'til I'll figure out how that Lewis scanner thing works!
Back to B200 topic: 5 scans per sec means a target at 300 m/s moves 60 m away per scan (if flying in perpendicular direction to C-25 site). Would that be too inaccurate even for a B-52, unless you have an interpolating computer or a nuke warhead?
Much more than 300m/s. The station is also tracking its missiles doing Mach4 flying out towards an expected Mach2 incoming enemy plane, so it had both.
Interpolating analogue target/missile tracking system (alltogether 40 channels).
Nuke warhead missiles (against formations).
