If the Islip radar is picking up boats on the water then wouldn’t it pick up trucks, buildings, what have you on land? And if it was doing that then wouldn’t the ground clutter tend to mask the aircraft it’s supposed to be picking up?

I don't know. Read the radar materials at Donaldson's site. It's pretty comprehensive.

They cross-referenced the Islip, JFK, and Westchester (HPN) radars, as well as the Newark (EWR) and other radar sites.
