Gabor schemes for analyzing antenna measurements

The oversampled Gabor transform (OGT) is proposed as a powerful tool for analyzing antenna measurements in amplitude and phase. The OGT allows to perform a high resolution analysis of the measured signal leading to the identification and the separation of its wave components. The proposed technique is applied to measurements performed in a semi-anechoic chamber to remove the reflected components and to retrieve the results one would have measured in a perfect anechoic chamber. In the application considered, the superiority of the OGT over the matrix pencil method is illustrated.
