A Three-Dimensional Imaging Method Based on Peak Detection for Multi-angle SAR

Spaceborne synthetic aperture radar (SAR) has been widely used in military reconnaissance, civil construction and scientific research because of its day and night, all-weather, and global observation capabilities. In order to reconstruct the third dimension of targets, a spaceborne multi-angle SAR system has been proposed. In this paper, a novel imaging method based on peak detection is proposed for multi-angle SAR system. The height error can affect the quality of the focused SAR images. The height of target can be obtained by searching the maximum position of the focused pixel. The effectiveness of the method is validated by simulated data.
