摘要 被动声传感器组成网络能够实现大面积区域的噪声监测,是一种有效的低空探测和环境监测手段,然而组网后信息融合技术在实际应用中面临若干问题。从工程应用角度出发,针对被动声传感器特点,分析了组网面临的时空配准、去除伪点、组网结构和并行计算等关键问题,并给出了合理的解决方法。 Passive acoustic sensors netting can achieve a large area of the noise monitoring. It is an effective method for low-altitude detecting and environmental monitoring. However, fusion technique after netting faces a number of problems in practical applications. Therefore, some practical problems, such as space-time registroration, deghosting, topological structure and parallel computing, which are towards characteristic of passive acoustic sensors, are analyzed in this paper. Some reasonable solutions are given.
