anyways, gonna tell you this: it has nothing to do with tracking, it is an search radar. tracking is done by directors or phased array radars or similar stuff. you can do tracking with SPY-1, but it is not designed to do so, and it does not operationally (as far as I know/remember)
if I see it correctly, SPY-1 does about exactly the same thing as that huge russian air search radar on top of your structure. and if it does not, there will be an huge russian air search radar that does!
Almost 100% incorrect. Impressive.
SPY-1 performs air search (and has evolved over the decades to be very good at this), but it was designed first and foremost as a tracking system.
