WebJan 1, 1996 · INTRODUCTION The Hapke model (Hapke, 1981; 1986; 1993) is a widely used model of soil bidirectional reflectance. Several inversion experiments have been carried out to retrieve soil physical parameters using this model (e.g., Pinty et al., 1989; Jacquemoud et al., 1992). WebThe empirical photometric function is fitted to the Hapke model over a portion of the visible hemisphere of an idealized planet using the following: INCMIN <= incidence angle <= …

WebNov 1, 2012 · Hapke (2012) fitted the centroid of this area by the empirical function (7) c = 0.05 b - 0.15 3 / 4 - 1. It is the purpose of this paper to investigate the c vs b correlation further. It will be shown that the correlation appears to be quite general for particles likely to be found in planetary regoliths, but that Eq. WebJun 1, 1991 · Here, researchers apply the Hapke function to airborne bidirectional reflectance data collected over three terrestrial surfaces. The objectives of the study were to test the range of natural surfaces that the Hapke model fits and to evaluate model parameters in terms of known surface properties. The data used are multispectral and … friday office funny meme
