Angle of Arrival Retrieval from Power Angular Spectrum Using Antenna Pattern Deconvolution at K-Band

In this paper, a simple deconvolution process for angle of arrival (AoA) retrieval is applied in an environment composed of up to five metallic poles to mimic a cluster of scatterers in the vicinity of the receiver. A measurement campaign was performed inside an anechoic chamber in two different configurations, and a deconvolution process was applied to the measured signal. Preliminary results at K-band show that the proposed technique can be used to effectively retrieve the angle of arrival in a controlled environment as well as the relative power between the direct and the reflected components, that are of most importance for angular spread evaluation so that the refinement of existing and new propagation models can be achieved. In future works, the algorithm will be tested within a polarimetric modelling of the propagation channel and will also be used to obtain the angular spread (AS).
