Requirements for Calculation of Coupling Coefficients for Generic Arrays from Infinite Array Scan Reflection Data

Planar array mutual coupling coefficients may be computed using scan reflection coefficient data from an infinite array code provided the limits of integration are defined appropriately. In most cases those limits extend outside visible space, imposing a requirement that boundary conditions be formulated in terms of u,v instead of thetas,Phi. Further, when the array lattice is skewed, an additional change of variable is needed to form a rectangular integration region. This paper describes the method needed for mutual coupling coefficient calculation and presents example results verifying the techniques
