<abstract>
<p>This paper introduces MHSRS&lt;sup&gt;2&lt;/sup&gt;F-V2, a new-generation indoor facility for multidirectional hyperspectral remote sensing simulation and HCRF measurement. Built around an 8 m-diameter hemispherical lamp array, the facility integrates the solar simulation, skylight simulation, observation simulation, scene simulation, and integrated control subsystems. Hybrid illumination units provide broadband illumination over 350&amp;ndash;2500 nm, with spectral correlation coefficients of approximately 0.928 and 0.912 for simulated sunlight and skylight, respectively. The facility supports coupled solar-skylight illumination, multidirectional observation, complex-scene construction, and both imaging and non-imaging payloads. Push-broom experiments produced spatially resolved HCRF image cubes of a physical sand-table scene and undisturbed rock samples, while multiangular ASD measurements revealed wavelength-dependent reflectance anisotropy. The results demonstrate the capability of MHSRS&lt;sup&gt;2&lt;/sup&gt;F-V2 for controlled HCRF measurement and physical simulation of airborne and spaceborne hyperspectral remote sensing.</p>
