Title: SAR azimuth antenna pattern estimation using a strong point target
Abstract: An alternative method to estimate the SAR azimuth antenna pattern (AAP) is presented in this paper. By applying time-frequency analysis to the echoes from a strong point target, the azimuth ambiguous problem can be solved and the algorithm is less affected by the background clutter. The method we proposed is not only much cheaper but also avoids the trouble of deploying and maintaining extra transponders, provided a strong point target, like a corner reflector, is already deployed in the calibration site. Finally, simulation experiment confirms that our method is correct and feasible.
