doi:10.11947/j.AGCS.2022.20210382

Abstract

Abstract: The control accuracy of distributed interferometric synthetic aperture radar satellite formation configuration maintenance is one of the key factors affecting the baseline length and thus the elevation measurement accuracy. According to the description and analysis of the relative orbital elements of formation dynamics, an unbiased four-pulse formation maintenance control method with independent in-plane and out-of-plane control is optimized and designed based on the traditional pulse control scheme. In particular, the coupling influence between relative orbital roots in the control process is compensated by combining with engineering practice, also the corresponding control strategy is formulated. The method has been applied to TH-2 system, and the correctness of the method has been proved by ground simulation and in-orbit data, so as to effectively ensure the expected distribution of interference baseline and provide guarantee for the smooth development of land elevation survey task.
