An accurate geophysical model is required to support calibration of a microwave imaging radiometer and retrieval of geophysical parameters. WindSat is a passive microwave imaging radiometer aboard the Coriolis satellite which was launched in January 2003. WindSat observations include dual-polarized antenna temperatures in two frequency bands (6.8 GHz and 23.8 GHz) and fully polarimetric antenna temperatures...
This paper examines the potential impacts of remote sensing, hyperspectral target detection from a physics-based modeling point of view. Often (atmospherically compensated) data is simply handed off to algorithm developers with the assumption that the data they are given accurately represents what transpired at the time of collection. In this paper, we discuss the various steps involved in processing...
Ground relief is a key parameter affects the open forest bidirectional reflectance factor (BRF) estimation result of a Monte Carlo ray-tracing model. In this proceeding, we propose a 3-D ray-tracing simulator for estimating the BRF for a forest with complex terrain relief. Unlike existing models, this model takes into account rugged terrain conditions by using a local normal retrieving approach based...
