The Automatic Identification System (AIS) for the development of high Frequency Surface Wave Radar (HFSWR) technology can provide verification data sets; At present, the existing means for HFSWR to provide data sets have shortcomings such as poor real-time and can only track and observe ships in a small range, etc. 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 ais 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 150m, the AIS information receiving distance of the system can reach 244km. The accuracy of the AIS maritime propagation model was verified; The ship-based ball-mounted AIS data acquisition system can realize long-term high-altitude residence, and the AIS information data of the vessels in the surrounding sea areas obtained 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.
