Standardization efforts to define radiated metrics and test methods for verifying millimeter-wave (mmWave) new radio (NR) devices are currently ongoing. Multiprobe anechoic chamber (MPAC) method, which is capable of reproducing spatial fading channels in the test zone, is selected as the reference solution for NR device testing. It is of importance to ensure that the defined testing propagation environment in the test zone is correctly implemented. In this communication, a novel algorithm is proposed to determine the wideband power-angle-delay profile of the reconstructed channels in the test zone for mmWave NR. The proposed algorithm is shown to be generic (applicable for both 2-D and 3-D testing setup), applicable for both near-field and far-field conditions and robust (i.e., insensitive to measurement distance errors).
