ABSTRACT:
A correlator for producing a correlation function by processing input data over a large number of coefficients of the correlation function by time sharing a smaller number of correlation channels, including a temporary storage device for receiving input data and for providing the input data as output data at particular successive time delay intervals relative to the input data, a group channel correlator responsive to the output data from the temporary storage device and to additional data for correlating the group of channels of data and for providing output sums representing coefficients of the correlation function, and means coupled to the temporary storage device and the group channel correlator for controlling the coupling of the output data from the temporary storage device to the group channel correlator to have the output data at the successive time delay intervals coupled to the group channel correlator to have the group channel correlator repetitively correlate successive groups of channels for providing the large number of coefficients in the correlation functions built up from the repetitive correlation of the successive groups of channels.
