I didn't know NASA had a phased array suitable for such surveys, but of course it's not really my gig -- astronomer, we don't transmit much! I mainly know about the Westford dish because it's used for VLBI and VGOS. I looked for a big NASA phased array, and couldn't find one other than the SOAR proposal. I couldn't figure out if it was actually built or not. Seriously, I'm interested in the details.
