Abstract :
Standard sites are important for antenna calibrations. However, many actual sites are not perfect for antenna calibrations due to surrounding reflectors and other measurement uncertainties. Earlier studies were either impractical for actual sites or calculating inaccurately. This paper develops a new method to compute normalized site attenuation (NSA) with reflectors nearby. Based on the conventional NSA, the model with the actual rod-like reflectors is formulated by the wave propagation theory, which is not considered earlier. With this new method, the interferences of rods are considered from the shortest reflected path. The results of the proposed method show good agreement with the numerical simulation results.
