Analysis of Tree-lined Road Extraction Capability Based on Aeronautical P-Band SAR Images

Compared with L-band, S-band, C-band, and X-band SAR satellites, P-band SAR has longer wavelengths and can penetrate leaf clusters and shallow surface, and may penetrate leaves and twigs on trees with certain spacing on both sides of the road. It can get road information that other shorter wavelength SAR can not reach. This paper studies the extraction of tree-lined roads using aeronautical high-resolution P-band SAR images. By comparing and analyzing the results of extracting tree-lined roads with different bands, it is shown that P-band SAR images can effectively extract tree-lined roads. It provides a scientific basis for the development of P-band SAR satellites.
