Research on A Special Hyper-Pixel for SAR Radiometric Monitoring

The objects presented in synthetic-aperture radar (SAR) images are the products of joint actions ground and SAR sensors specific geospatial contexts. With accumulation massive time-domain data, scholars have opportunity to better understand ground-object targets sensor systems, providing some useful feedback for SAR-data processing. Aiming at normalized low-cost radiometric monitoring, this paper proposes a new hyper-pixel concept handling multi-pixel ensembles semantic targets. special study refers low-rise single-family residential areas, its radiation reference is highly stable time domain when other dimensions fixed. stability data can reach level 0.3 dB (1σ), as verified by multi-temporal from Sentinel-1. A comparison with tropical-rainforest availability possible variations radiation-intensity shifts Sentinel-1B ere experimentally monitored. In paper, effects seasonal climate relative geometrical states observed on intensity hyper-pixel’s investigated. This novel processing interpreting SAR-image data. proposed shown be multi-temporal-data observations monitoring has potential used cross-calibration, addition applications.
