  Yep "drift scanning" :) A single dish/node can't really produce photograph-like imagery akin to an optical telescope, more often[1] you get something like in the setileague website hits [2].

  The CHIME telescope[1][2] is an example of that. It's a bit more advanced though, the multiple antennas allows them to "steer" the antenna after the fact through signal processing.
