舰船水下轴频电场探测效能分析OA

To address the performance evaluation and optimization requirements of underwater shaft-rate electric field detection systems for ships,propagation modeling and detection efficiency analysis are conducted.A propaga-tion model for underwater shaft-rate electric field of ships in stratified media is first established,and the received electric field level of sensors is derived and calculated.Subsequently,simulation analysis is performed on the influ-encing factors during sensor deployment at sea.Results demonstrate that compared with single-channel sensors,cross-deployed dual-channel sensors can significantly improve system robustness,with detection range enhanced up to 3.5 times under high detection probability conditions.Furthermore,among various influencing factors,changes in sensor deployment angle and spacing have significantly greater impact on detection performance than variations in center distance between sensors.These findings provide a theoretical basis for optimized deployment and performance enhancement of underwater shaft-rate electric field detection systems.
