Along-track Orbit Prediction Error Correction of Space Targets Based on Translational Motion Phase

Inhalt:
Accurate orbit prediction is extremely important in interferometric inverse synthetic aperture radar (InISAR) imaging of space targets. However, the along-track orbit prediction error of space targets can reach up to several kilometres in some cases. To solve this problem, a correction method for the along-track orbit prediction error based on the translational motion phase of the space target has been proposed. The correction method could reduce the along-track prediction error from several kilometres to several hundred metres, then the three-dimensional model of space target can be reconstructed within an acceptable accuracy. Simulation results verify the effectiveness of the proposed method.
