摘要
坐底式声学波潮仪采用遥测方法进行表层波浪测量,不干扰波浪场,测量准确度高。现有国产声学波潮仪只具备波高、波周期和潮汐测量能力,欠缺波向测量功能。针对仪器国产化需求,研制一种新型坐底式波潮仪,可同时测量波高、波周期、波向、潮汐和温度,是一种先进的海洋监测设备。本文采用基于多向不规则波的仿真模型对比声学波潮仪和诺泰克浪龙的方向谱反演能力,2019年3月在山东省海洋环境监测技术重点试验室下属岸边试验站进行比测试验,比测仪器为挪威诺泰克浪龙,实测数据分析表明,声学波潮仪和诺泰克浪龙总体上吻合好,验证了声学波潮仪的波浪测量准确性。
The acoustic wave instrument uses remote measurement to measure surface wave without disturbing the wave field and has high measurement accuracy.The existing domestic acoustic wave instrument only has the ability to measure wave height,wave period,and tide,but lacks wave direction measurement ability.In response to the need for localization of the instrument,the research and development of a new bottom-mounted acoustic wave instrument is carried out.The new type acoustic wave instrument can simultaneously measure wave height,wave period,wave direction,tide,and temperature.It is an advanced marine monitoring equipment.This paper compares the wave directional spectrum inversion capabilities of acoustic wave instrument and NortekAWAC through a simulation model based on multi-directional irregular waves.In march 2019,a comparative test with Nortek AWAC at the shore test station under the Shandong Provincial Marine Environmental Monitoring Technology Key Laboratory was done.Sea test shows that the acoustic wave instrument and Nortek AWAC are generally in good agreement,which verifies the wave measurement accuracy of the acoustic wave instrument.
