Elevation Information Extraction Scheme Based on Sub‐Aperture Correlation Using Airborne Circular Synthetic Aperture Radar Imaging
Hongtu Xie, Qi Peng, Yangyang Xiao, Nannan Zhu
ABSTRACT Airborne circular synthetic aperture radar (CSAR) enables multiangle observation and high‐resolution imaging, which can extract the elevation information. However, the traditional elevation extraction methods are limited by the low elevation extraction accuracy and complicated processing flow. Thus, an elevation information extraction …
