【摘要】：针对常用的卵石运动观测技术在时效性与时空同步性等方面存在的不足,结合当前追踪技术,提出一种实时定位的卵石运动观测方法。基于声波在水中传播的独特优势,采用水声信号对水下目标进行实时追踪。由安装有声波发射器的卵石以及近水面布置的多个声波接收器构成卵石运动实时追踪系统,根据冗余观测数据的最小二乘解推求卵石位置,以实现卵石运动实时追踪。经过初期现场测试,验证了追踪模型以及算法的有效性。
[Abstract]:In view of the shortcomings of the commonly used pebble motion observation techniques in terms of timeliness and space-time synchronization, a real-time locating pebble motion observation method is proposed, which is based on the unique advantages of acoustic wave propagation in water. The underwater target is tracked by underwater acoustic signal in real time. The pebble motion tracking system is composed of pebbles with acoustic transmitter and several acoustic wave receivers arranged near the water surface. Based on the least-square solution of redundant observation data, the pebble position is deduced to realize the pebble motion real-time tracking. The validity of the tracking model and algorithm is verified by the initial field test.
