A method for the calculation and accurate prediction of the noise coupling in a phased antenna array is introduced. The noise coupling is shown to be related to the scan reflection coefficient, a measurable antenna parameter. This leads to a method of calculating the noise coupling of the array using scattering parameters, which can then be used in design of a receive-mode phased array. A 49-element dipole array at 1 GHz using HPMGA-82563 LNAs is used as an example to calculate the parameters of interest for a low-noise phased array design.
