This research memorandum describes a data processing technique for analyzing the Doppler-shift properties of a radio channel. A computer program has been developed that computes the power spectrum of power scattered by the radio channel as a function of Doppler shift. This program was developed in conjunction with phase-stable CW experiments which were performed on two HF paths. The program computes the power spectrum of the time variations of the response of the radio channel to a CW tone relative to the transmitted frequency.
