Abstract
En 中文
The line spectrum of ship-radiated noise can be used in passive sonar to detect ship targets; however, it is affected by ocean noise and the Doppler effect, which has a negative effect on target detection. In the paper, the multi-channel data of a single vector sensor is used, and the line spectrum detection algorithm based on singular value difference in frequency domain is proposed for detecting ship targets. The simulated and experimental results show that the proposed algorithm can be used to detect line spectrum under Doppler and background noise interference. The proposed algorithm can provide feasible and low-cost line spectrum detection results in engineering applications, which ensures the certainty of passive detection by using this method.
