摘要
为了实时获取海气分界层气象水文参数,计算修正折射率指数廓线从而现场评估蒸发波导对海上电磁波的传播影响,设计了蒸发波导环境监测与诊断系统。该系统基于ZigBee技术进行多传感器组网,可以测量不同高度层的温度、湿度、气压参数,采用自适应卡尔曼滤波算法解算测量终端姿态,通过计算快速获取蒸发波导高度、强度参数,具有实时性强、测量范围广等优势。实验结果表明,一般海况下该系统可以满足测量要求,为蒸发波导环境实时监测与诊断提供了新的硬件方法。
In order to obtain the meteorological and hydrological parameters of the air⁃sea boundary layer in real time and calculate the profile of modified refractivity index,so as to evaluate the influence of the evaporation duct on the electromagnetic wave propagation on the spot,an environment monitoring and diagnosis system for the evaporation duct is designed.The system is based on ZigBee technology for multi⁃sensor networking,which can measure temperature,humidity and air pressure parameters at different altitudes.The adaptive Kalman filtering algorithm is adopted to calculate the measurement terminal posture,and the height and strength parameters of the evaporative duct are quickly acquired by calculation.Thus,the system has the advantages of high real⁃time performance and wide measurement range.The experimental results show that the system can meet the measurement requirements under normal sea conditions and provides a new hardware⁃based method for real⁃time monitoring and diagnosis of evaporation duct environment.
