Abstract
The momentary Fourier transform computes the DFT of a discrete-time sequence for every new sample in an efficient recursive form. We describe the arithmetic requirements of the MFT, and give examples where it is more efficient than the FFT. We describe how DFTs are used in the SPECAN method of Synthetic Aperture Radar (SAR) processing, which includes overlapped inverse DFTs. We apply the MFT to SPECAN processing and show what advantages and disadvantages it has compared to the FFT.
