ABSTRACT:
A signal processor for generating the ambiguity integral using a modulatable, broadband, incoherent light source, a multiplicity of acousto-optic cells and diffraction gratings, and a two-dimensional time-integrating photodetector array. The various colors of the source spectrum are shifted by differing radio frequencies. These modified spectral components are also modulated by an input signal and serve as input sources for performing a multiplicity of correlations using an acousto-optic cell with an unknown Doppler-shifted signal. The answer is displayed on a two-dimensional time-integrating photodetector array where the spectral components are dispersed within the columns. The row corresponding to the color that has been properly frequency-compensated will contain the correlation or ambiguity peak, thereby identifying the Doppler component. Position within the row determines range.
