As a second generation of China's polar orbiting meteorological satellite, the satellite of FY-3A and FY-3B were launched in 2008 and 2010, sequentially, in sun-synchronous orbits located at the altitude 831 km. The FY-3A/B load totally 11 sensors, including microwave sensors, such microwave temperature sounder (MWTS), microwave humidity sounder (MWHS) and microwave radiometer imager (MWRI), etc.
Numerical study of radar echoes from the targets in environmental clutters has been of great interest in many applications. In this paper, the bidirectional analytic ray tracing (BART) method for composite scattering from three-dimensional (3D) electrically large complex target above a randomly rough surface is reported. Analytic tracing of polygon ray tubes in bidirectional tracing is developed to...
This paper presents a hybrid iterative algorithm of analytic Kirchhoff approximation (KA) and numerical method of moment (MoM) for scattering computation from a three-dimensional (3D) perfect conducting target above a randomly rough surface. The coupling integral equations (IEs) are derived based on the Green's function and the boundary conditions. The MoM with the conjugate gradient (CG) approach...
