Efficient modeling of array manifold is the essential prerequisite for the array signal processing.Due to the variable curvature of the platform and different orientations of elements

the most serious challenge faced in the modeling of array manifold for conformal array antenna is the element polarized pattern modeling in the global referenced coordinates.A uniform frame of the rotation transformation of the global Cartesian coordinates to the element local Cartesian coordinates is first established with the help of the Euler rotation.The rotation transformation of the polar coordinates of the global array to the local elements and the polarized pattern rotation of the local to the global coordinates are realized subsequently.The modeling method proposed is verified with the simulation of inherent shade effect of circular cylinder conformal array antenna.
