Abstract:

An algorithm is developed for computing the cross correlation between a given digitally recorded signal and a set of standard signals of the form S omega, alpha, t exp iomega t alpha t squared, corresponding to a signal whose frequency varies linearly with time. A code is presented for the CDC 6600 computer, and discussed sufficiently to enable programs to be written for other machines. Text data is included for debugging purposes. Author
