Claim 5:
6. The method for evaluating sonar self-noise at a ship design stage according to claim 1, wherein step S6 specifically comprises:
solving average energy values at 100 Hz, 1 kHz, and 10 kHz frequency points in the total spectral density level of the sonar self-noise, if the average energy value is less than 3 dB or more of the preset index requirement, continuing the next stage of operation, wherein the preset index requirement can be implemented, if the average energy value is less than 3 dB or less of the preset index requirement, continuing the next stage of operation, wherein the preset index requirement has a risk, and otherwise, the preset index requirement has a high risk, then iteratively optimizing steps S3 to S6 before evaluation.
