Abstract
FIELD: mechanics.SUBSTANCE: hydroacoustic Doppler log incorporates transceiver antennas, master oscillator, radiated signal power amplifier, receiver amplifier and display. Note that the log radiating circuit comprises heterodyne and mixer, while the receiving log incorporates additionally a mixer connected to the input amplifier and master oscillator and rejection filter tuned to the frequency of aforesaid heterodyne.EFFECT: higher noise-immunity of continuous-radiation logs, higher accuracy of measuring ship speed of log operating depth.2 dwg
