Title:
APPARATUS FOR CALCULATING DISCRETE FOURIER TRANSFORM AND PULSE COMPRESSION RADAR SYSTEM UTILIZING THE SAME
Document Type and Number:
Japanese Patent JPS6293755
Kind Code:
A
Abstract:
A device for calculating a discrete, moving window and non-recurrent Fourier transform, especially applicable to the processing of a pulse compression radar signal. The device includes N stages which, on the basis of samples of the input signal, each give a signal of the form: (1) with: X'km+1 = X'km + x'm+N - x'm (2) (3) where k is the index of the stage (O
