Abstract
The cosine window function with the parameters opti- mized by Genetic Algorithm (GA) is applied in bistatic planar near- fleld scattering measurements so as to efiectively improve the mea- surement precision. With the inflnitely long ideal conductor cylinder as the target under test, the bistatic planar near-fleld scattering mea- surement technique is studied by the method of computer simulation and some useful results and basic laws are obtained. The calculation results show that the truncation errors caused by flnite scan plane in the far-fleld Radar Cross Section (RCS) of the target under test ob- tained by near-fleld to far-fleld transformation can be reduced greatly by the weighting process of the measured scattered near-fleld data by means of the cosine window function with the parameters optimized by GA.
