【摘要】：針對常用的卵石運動觀測技術(shù)在時效性與時空同步性等方面存在的不足,結(jié)合當(dāng)前追蹤技術(shù),提出一種實時定位的卵石運動觀測方法�；诼暡ㄔ谒袀鞑サ莫毺貎�(yōu)勢,采用水聲信號對水下目標(biāo)進(jìn)行實時追蹤。由安裝有聲波發(fā)射器的卵石以及近水面布置的多個聲波接收器構(gòu)成卵石運動實時追蹤系統(tǒng),根據(jù)冗余觀測數(shù)據(jù)的最小二乘解推求卵石位置,以實現(xiàn)卵石運動實時追蹤。經(jīng)過初期現(xiàn)場測試,驗證了追蹤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.
