摘要
船舶自动识别系统可以为发展高频地波雷达技术提供验证数据集;目前,现有手段为HFSWR提供的数据集存在实时性差以及仅能对小范围内的船只进行跟踪观测等缺点,针对该问题,设计了一套船基球载AIS数据采集系统,利用系留球搭载AIS接收机进行多次海上长时间驻空实验,期间获取了来自345条船只的270580条数据;结果表明:船基球载AIS接收机这一方式能够显著提高船只之间AIS信息的接收距离,当系留球锚泊在150 m高空时,系统的AIS信息接收距离能够达到244 km;并验证了AIS海上传播模型的准确性;船基球载AIS数据采集系统可实现长期高空驻留,所获取的周边海域船只的AIS信息数据范围广,实时性高,漏报率低,是对船基HFSWR性能进行评估的有效手段。
The Automatic Identification System(AIS)for the development of high Frequency Surface Wave Radar(HFSWR)technology can provide verification data sets;At present,existing means for HFSWR to provide data sets have shortcomings of poor real-time,and tracking and observing ships in a small range.In view of this problem,a set of ship-based ball on-board AIS data acquisition system is designed,and multiple long-term air-dwelling experiments at sea are carried out using tethered balls and AIS receivers,during which 270,580 pieces of data from 345 ships are obtained;The results show that the receiver on board the ship-based ball can significantly improve the receiving distance of AIS information between ships,and when the tether ball is anchored at a height of 150 m,the AIS information receiving distance of the system can reach 244 km.The accuracy of the AIS maritime propagation model is verified;The ship-based ball-mounted AIS data acquisition system can realize long-term high-altitude residence,and the obtained AIS information data of the vessels in the surrounding sea areas is wide-ranging,high in real-time,and low in under-alarm rate,which is an effective means to evaluate the performance of ship-based HFSWR.
