The invention discloses a radar prow interference suppression method, which comprises the following steps: determining a radar distribution position according to a prow structure, adjusting the radar distribution position according to the number and position of prow interference sources, and determining the number of radars according to a radar coverage range requirement and a required radar frequency band; determining a corresponding frequency band according to the coverage range of each radar, and enabling a plurality of radar frequency bands to achieve the comprehensive coverage of the bow position; the radar orientation and elevation angle are confirmed based on the radar distribution position and the coverage area requirement, so that radar signals can be received in the bow direction; adjusting the beam scanning rate and the repetition period of the corresponding radar based on the interference source signal frequency, adjusting the pulse width of the corresponding radar, and adjusting the radar frequency band based on the distance change parameter of the detection echo; and determining the power of a receiving amplifier according to the radar echo receiving frequency, and carrying out corresponding radar signal processing. The interference frequency of the prow radar can be reduced.
