Abstract :
This paper proposes a new multi-angular & multi-spectral BRDF model (ASK Model) base on the kernel-driven conception, and outlines an algorithm suitable for broadband albedo retrieval with the new model. By adding component spectra into kernels as prior known driven variables, the new model express BRDF as a linear combination of wavelength independent kernel coefficients and kernels expressed as functions of both observation geometry and wavelength.
