Experimental results of a 112 element phased array feed for the Westerbork Synthesis Radio Telescope

This paper presented the progress in the characterization of a prototype PAF system: overlapping compound beams, sensitivity over the field of view, single dish imaging and fringes between the PAF system and multiple horn fed dishes. The development and characterization of phased array feeds is an ongoing effort. The results presented in this paper are an important step in demonstrating the feasibility and competitiveness of the PAF for radio astronomy.
