ABSTRACT:
A device which provides bidimensional correlation of an image obtained by the scanning of electromagnetic or acoustic waves of the reference image. The scanned image and the reference image are written into memories with a pair of memories storing the real and imaginary portion of the signal of the corresponding images. After analog conversion, the signals are placed on a carrier and correlated in a line-by-line manner through the use and elastic wave convolver. The output of the convolver is demodulated with a correlation signal being applied to an adder and the correlation image being stored with its real and imaginary portions in a set of memories to provide a bidimensional correlation of an image.
