With the development of acoustic stealth technology and underwater acoustic countermeasure technology, the detection performance of monostatic sonar system for low-noise targets is difficult to meet the operational requirements, while the comprehensive detection of multistatic system may greatly improve the detection performance, which provides a new way to solve the detection problem of a quiet target. Therefore, a fusion detection algorithm based on vector hydrophone for multistatic sonar system is proposed in this paper. The detection performance of four kinds of sonar systems is compared, which are monostatic distributed, monostatic centralized, multistatic distributed and multistatic centralized. Detection performance is quantitatively analyzed by the detection range of detection probability above the detection threshold. The research has a certain reference value for large-scale target detection.
