Figure Dataset for High-ASRF Y-Shaped Interferometric Array Design and Dual-Aperture Collaborative Brightness Temperature Reconstruction

The figures present the design principles and configurations of high aperture-to-sampling-interval ratio (ASRF) Y-shaped interferometric arrays, including two types of multi-column array configurations, their baseline distributions, hexagonal spatial-frequency sampling grids, and baseline-coverage characteristics.

The dataset also includes figures illustrating the small-aperture auxiliary array, dual-aperture collaborative brightness-temperature reconstruction, simulated brightness-temperature maps, and quantitative reconstruction-performance analyses.All figures were generated from the numerical simulations and analyses described in the manuscript. The dataset is intended to support the interpretation, verification, and reproducibility of the reported results for research on interferometric radiometry, sparse-array design, spatial-frequency-domain sampling, and microwave brightness-temperature imaging.
