An inverse scattering problem of determining the electrical property of an unknown dielectric object is considered. The electromagnetic wave generated by an impressed electric current with a short duration time illuminates the dielectric object. The measured data of the total field, the sum of the incident and scattered fields, over an observation surface S is used to reconstruct the electrical property...
The analysis of the tolerance effects on the radiated power pattern caused by the fabrication errors in the printing of the microstrip patches of reflectarrays is addressed through a method based on the Interval Analysis and the arithmetic of intervals. The dimensions of the microstrip patches are defined as intervals of values including the tolerance errors and the mathematics of intervals is exploited...
A time-reversal approach to reconstructing the electrical parameters of an inhomogeneous object from measured total field data is considered. It is shown that the approach does not require the information of the incident field in the region of interest enclosing the object when the primary source is placed outside of the region. Numerical simulations are performed to validate the effectiveness of...
Calibration method for spaceborne polarimetric SAR data using a genetic algorithm is discussed in this paper. Recently some satellites which have polarimetric synthetic aperture radar were launched, and the polarimetric data analysis techniques are being developed for terrain classification, forest biomass and soil moisture estimations, etc. Thus, polarimetric calibration becomes an important issue...
