Abstract

Abstract

The spatially separated observation angles from the multiple inverse synthetic aperture radar sensors can be converted to the accumulation time of the same target, which can improve the cross-range resolution of ISAR image by the coherent fusion of raw echo signals collected from different sensors. To solve the issue of multiple radar sensors coherent fusion ISAR imaging of space target moving on orbit, the radar location optimal method based on the orbital prior of the space target is proposed to improve the efficiency of the echoes fusion, the spatial- variant property of the fusion imaging plane of space target is analyzed using orbital motion model to solve the range Migration Through Resolution Cells (MTRC) and time-varying Doppler. The simulation results based on real orbit of space station confirm the effectiveness of the proposed method.
