Height-measure Accuracy Analysis of Distributed Spaceborne InSAR System

摘要：

Distributed spaceborne interferometric synthetic aperture radar(InSAR)system includes more than one baseline, so it is also called multi-baseline InSAR system. It offers additional observation information for the derivation of position and height of the object. The influence of the additional information to heightmeasure accuracy is analyzed by first order approximation. The influence of the baseline attitude on the measurement accuracy is also analyzed and a profile which describes the relationship between height measurement accuracy and baselieng attitude angles is given. Signal simulation is made to validate the analysis results and error spread coefficients of singlebaseline and multi-baseline system are listed for comparison. Results show that the additional information of the distributed InSAR system can reduce the error sensitivity of the single-baseline system.
