Windowing functions for focused range-Doppler imaging

摘要

A method for obtaining windowing functions for focused range-doppler imaging of rotation objects is given. Focused range-doppler imaging of rotation objects involves the evaluation of a non-standard transform rather than the discrete Fourier transform. As such, familiar windowing functions such as Hamming are inappropriate for sidelobe control. Previous methods of evaluation involve resampling and interpolation to emulate the discrete Fourier transform. In this paper, a correction factor applied to any standard window function is derived and results shown.
