In this paper, based on actual geometrical condition for master satellite and distributed small satellite SAR system, height measure principle is established. Based on geometrical condition of relative height measure, the relations between relative height accuracy and interferometric phase error are deduced. Then, noise decorrelation, baseline decorrelation and pixel misregistration decorrelation and so on, are analyzed, and the image correlation coefficient is deduced. Finally, the effect of image decorrelations to relative height accuracy is analyzed, the results indicate, for flat surface, noise decorrelation and pixel misregistration decorrelation are the main factors, and baseline decorrelation is the minor factor. %K Distributed small satellites %K SAR Interferometry %K Relative height accuracy %K Decorrelation
