| Abstract: | In this paper, a relationship between the cumulative probability of sidelobe of a module array antenna and the range of element position errors, subarray position errors and the phase errors of each element is discussed. The expression of the relationship between element position errors, subarray position errors and total position errors is derived. The computation and simulation results show that the phase error and amplitude error in each element, element position error and subarray position error are all very critical for an ultra-low sidelobe array antenna with subarrays. |
