Abstract :
In InISAR (Interferometric ISAR), in order to get higher calibration accuracy, the baseline of two interferometric antennas should be long enough, causing the problem of de-correlation of baseline and mismatching between interferometric images. The de-correlation is analyzed in this paper. The method of image matching based on correlation is given to solve the problem of image mismatch caused by baseline de-correlation. The effectiveness of this method is proven through simulation.
