Estimation of Atmosphere and Object Properties in Hyperspectral Longwave Infrared Data

Abstract

We present a method for atmospheric estimation in hyperspectral longwave infrared (LWIR) data. The method also involves the estimation of object parameters (temperature and emissivity) under the restriction that the emissivity is constant for all wavelengths. The method is analyzed with respect to its sensitivity to noise and number of spectral bands. Simulations with synthetic signatures and signatures from real vegetation are performed to validate the analysis.
