| Popis: | 92 Antenna measurement inside an anechoic chamber with a limited space generally suffers from multipath interferences due to the scattering from the shielding walls and internal structures if the quality of the absorbers is not very well. This paper develops a hybrid scheme that integrates concepts of signal process techniques including time gating, matrix pencil and multiple signal classification methods to reduce the multipath effects and improve the measurement accuracy. Characteristic comparison between individual method as well as the hybrid scheme will be performed based on experimental examinations. |
