Height Measurement Performance Analysis And Software Design Of Spaceborne Interferometric Synthetic Aperture Radar System

In recent years,the spaceborne synthetic aperture radar technology has continued to develop,and it is used more and more broadly in people's production and daily life because of unmatched advantages in agricultural production,biomass measuring,terrain surveying,disaster monitoring and other areas.The analysis and design method of the satellite-borne interferometric synthetic aperture radar system is an important prerequisite for the construction of a suitable satellite-borne interferometric synthetic aperture radar system.How to design the spaceborne interferometric synthetic aperture radar system performance analysis software are main research directions of the thesis.The main works are as follows:1.The thesis introduces the theory of interferometric synthetic aperture radar.The interferometric synthetic aperture radar model considering the curvature of the earth is derived.Performance parameters of the interferometric synthetic aperture radar system are analyzed.Their errors classification method and impact on final performance are discussed in detail.2.According to the theory of spaceborne interferometric synthetic aperture radar,the Thesis research suitable interferometric synthetic aperture radar model and satellite orbit model to design appropriate algorithms,that combines with the object-oriented programming method to design a flexible and practical spaceborne interferometric synthetic aperture radar performance analysis software which can have multiple analysis methods of the parameters of the spaceborne interferometric synthetic aperture radar system.3.The new P-band SAR satellite BIOMASS is analysed with performance analysis software.A multi-satellite suitable interferometric synthetic aperture radar system is found for BIOMASS,and its performance is analyzed with the analysis platform software,including the performance changes during the operation cycle of the two kinds of formation configurations.The performance of their is compared to the performance of repetitive orbit spaceborne interferometric synthetic aperture radar system.Through the above works,the thesis researches and designs a performance analysis software which can provide a platform for analyzing and help to design interferometric synthetic aperture radar system efficiently.a reference scheme of multi-satellite formation interferometric synthetic aperture radar system suitable for BIOMASS is put forward.
