The invention relates to a clock synchronization and pulse control signal generation method for an underwater acoustic ranging system, and the method comprises the steps: receiving a pulse per second and an NMEA-0183 parameter outputted by GNSS equipment through a clock synchronization module, analyzing time information through the NMEA-0183 parameter by a time analysis unit, and transmitting the time information to a clock synchronization and time information generation unit, the clock taming unit carries out clock taming by using the pulse per second output by the GNSS equipment and outputs the pulse per second to the clock synchronization and time information generation unit, and the clock synchronization and time information generation unit outputs a pulse per second signal and time information to the underwater acoustic machine; and the pulse generation module periodically outputs pulse signals according to second pulse signals output by the ranging parameter configuration and clock synchronization and t
