  • Analog SAR echoes are usually sampled in both azimuth and range for digital processing, which will introduce error to point target peak measurements. This problem is analyzed in detail and the theoretical relationship between peak error and target location is given. For time-divided mode polarimetric SAR systems, azimuth sampling will also introduce relative error between different polarization data. A match-filtering method is proposed, which uses different time-delayed filtering functions for different polarization data, to produce the same effect of azimuth sampling on them. Simulation results prove its effectiveness in improving the magnitude and phase consistency.
