Abstract
A device for computing a nonrecursive and sliding discrete Fourier transform as applicable in particular to processing of a pulse compression radar signal has N identical and parallel stages (E.sub.k) for receiving in each case samples of the input signal (e.sub.m+N). Each stage comprises two complex rotation operators, two adder-subtracters and two delay circuits and delivers a signal X.sub.k.sup.m+1 obtained from the following equations: ##EQU1##
