access icon free Fast implementation of scaled inverse Fourier transform for high-speed radar target detection

The symmetric autocorrelation function (SAF) has a huge computational complexity, which may limit the practical application of SAF-based scaled inverse Fourier transform (SCIFT). Taking the relationship between SAF and summation into consideration, a frequency-domain method is proposed for the fast implementation of the SCIFT, and the energy integration performance remains unchanged. Mathematic analysis and numerical simulations are provided to illustrate the efficiency of this method.
