Abstract | Phased array feed is a small phased array placed at the focal plane field of the radio telescope. Its field of view can be understood as the maximum scanning angle that the array can achieve combined with the radio telescope. When the aperture is 25m, the focal diameter ratio is 0.3 and the working frequency is 1.25GHz, the design of Phased array feed can realize the scanning range of one beam width, so as to determine the array size of phased array feed. 5×5 and 9×9 rectangular array arrange evenly within this size range, which can scan a beam in different directions by exciting different subarrays. By comparing the beam deviation angles and beam width under the two arrangement modes, we can see that 9×9 arranged PAF array will eventually expand the number of beams included in the field of view of the telescope from 0.96-1.25 of 5×5 array to 1.54-2.9. The related work has a certain guiding role for array design and field of view optimization for phased array feed. |
