MARU-Net: Multiscale Attention Gated Residual U-Net With Contrastive Loss for SAR-Optical Image Matching

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Accurate synthetic aperture radar-optical matching is essential for combining the complementary information from the two sensors. However, the main challenge is overcoming the different heterogeneous characteristics of the two imaging sensors.

Multi-Temporal Sentinel-1 and -2 Data Fusion for Optical Image Simulation

open access: yesISPRS International Journal of Geo-Information, 2018
In this paper, we present the optical image simulation from synthetic aperture radar (SAR) data using deep learning based methods. Two models, i.e., optical image simulation directly from the SAR data and from multi-temporal SAR-optical data, are ...

Optical cements for interferometric applications [PDF]

open access: yes, 1984
The wave front distortion introduced by optical cements is important in interferometric applications. We describe here tests performed to characterize two common cements, Epo-Tek 301 and Norland Optical Adhesive ...
