The invention discloses a satellite-borne laser communication terminal and a signal processing method thereof, which are used for improving the receiving sensitivity of a system in a low-speed mode and greatly reducing the power of a corresponding transmitting end so as to meet the low power consumption requirement of the system. The terminal comprises a signal processing device, a transmitting module, a receiving module and a receiving and transmitting light path, and the signal processing device is used for generating baseband signals with different transmitting rates and transmitting the baseband signals to the transmitting module; the transmitting module is used for modulating the baseband signal into a first optical signal with a corresponding wavelength according to a transmitting rate and transmitting the first optical signal to the receiving and transmitting optical path; the receiving and transmitting optical path is used for converting the first optical signal transmitted by the transmitting module
