Define larger ship? There's a version in service for frigate sized ships (5kton). There was even a version designed for corvette sized ships.
The problem isn't the size. It's the cost. It's expensive enough that making the ship a bit bigger gets you a bunch more capability for not much more cost.
The direct comparison for ground mobile would probably be the TPY-2 radar.
