In the paper the scattering characteristics estimation for scale model of Mi-8MT helicopter was carried out for measurements in an anechoic chamber. The description of the experimental measurement system, the methodology of measurement, and the analysis of obtained experimental results are represented. In addition, the features of scattering characteristics are obtained and helicopter design influence are estimated for scattering characteristics of test model. The scattering characteristics of the Mi-8MT were calculated numerically also. The calculations are based on the integral representations of classical electrodynamics and high-frequency asymptotics of scattered fields. These results show an acceptable coincidence between the theory-obtained values and experimental data and confirm the ability of using proposed experimental method of scattering characteristics estimation for aerial object models with complex shape.
