  • Method and system for measuring doppler frequency shift of an echo
    Patent number: 4016568
    Abstract: A beam of diverging electromagnetic radiation of a predetermined frequency is transmitted to a target and the doppler shift of frequency of an echo due to relative movement of the target and a point of reception is detected conventionally by combining the frequency of the echo and the predetermined frequency. The number of cycles within the detected doppler shift frequency is counted to provide a delay to initiate measurement of doppler shift at a preselected angle of incidence of the echo. The effective area of measurement is thus restricted to a narrow region of the beam with the resultant high degree of precision.
