The development of new outdoor millimeter-wave channel models requires processing of the experimental data which can be used to estimate multipath channel parameters with very high time and angular resolution. The virtual antenna arrays processing technique allows joint narrow beam forming and beam steering. The specific of outdoor experiment does not allow precise positioning of the antennas, like it possible under lab-conditions. So some special methodology should be developed to overcome this problem. In this paper we propose the virtual antenna array signal processing which allows for given experimental data to perform environment scanning with equivalent 1 degrees antenna beamwidth and -30dB sidelobes rejection. As a result, the measurement environment was accurately reconstructed on the base of measurement data. High angular resolution of the proposed virtual antenna array signal processing allows estimating the wall-reflected rays (channel clusters) power-angular spectrum parameters for a Laplacian model.
