Reconstruction of three-dimensional free space radiation pattern using non-anechoic measurements factored by the impulse response of the environment

The objective of this paper is to reconstruct the free space radiation pattern from non-anechoic measurements in three-dimension (3D) using the impulse response both in the time and angular domains of the non-anechoic environment. This methodology could reconstruct two-dimension (2D) radiation pattern of antenna under test (AUT) characterized in non-anechoic environment and we extend it to reconstruct 3D radiation pattern. A numerical example is presented to show that the method is applicable for 3D pattern reconstruction.
