Abstract

A multi-temporal analysis of Sentinel-1 images (VV polarization) was conducted to monitor activity at the Chinese naval base in Yulin between January 2024 and June 2025. By constructing a time series of radar backscatter in decibels, variations compatible with the presence or absence of naval units were detected. The observed reflectivity peaks are consistent with events documented by OSINT sources, indicating strategic movements and periods of high operational activity.
