摘要

本文研究了一个需要高度重叠逆dft的雷达处理实例。这种情况出现在突发模式合成孔径雷达(SAR)中，其中接收数据的时变光谱特性要求idft位于光谱域的特定点上。介绍了傅里叶反变换，并说明了它在雷达应用中如何比FFT更有效。

Application of the momentary Fourier transform to SIFFT SAR processing

This paper considers a case of radar processing which requires highly-overlapped inverse DFTs. This case arises in burst-mode synthetic aperture radar (SAR), where the time-varying spectral properties of the received data requires that IDFTs be located at specific points in the spectral domain. The inverse moving Fourier transform is introduced, and it is shown how it can be more efficient than the FFT in this radar application.
