  • A baseline design method is proposed for the spaceborne small satellites formation INterferometric Synthentic Aperture Radar (INSAR). This technique is based on the space geometry of the small satellites formation and the real geographic model. An analysis is given to the characteristic of the interferometric echoes, the method of choosing the critical and optimal baseline is also presented. The effect of the equivalent number of looks, signal to noise ratio and the topographic slope is also analyzed. Simulation design is carried out according to the C-band small satellites formation, in one orbit period, the variation of interferometric baseline and the elevation precision are presented. The simulation results validate the effectiveness of this baseline design method.
