As the stepwise progress of oil - gas exploration, more and more attention has been paid to the multi - component seismics of ocean bottom cable ( obc ), and this technology has become a new aspect of the marine seismic prospecting
隨著油氣勘探的逐步深入，海上多波地震勘探技術越來越受到重視，發展海上多波勘探成為海洋地震工作的新方向，對海底檢波器的二次定位研究是海上多波地震勘探工作中必不可少的一環。Real time seafloor tracking technique is the critical technique to ensure smooth seafloor surveying with full coverage and high efficiency. after detailed investigation on stochastic features of seabed reverberation produced by mbss systems, the author presented an algorithm and a set of relevant key coefficients for real time seafloor tracking, taking into account of characteristics of signal processing and timing sequence of the real system and introducing theorems of terrain surveying. as an achievement, a mathematical model was established based on the technique of centered filtering
海底地形實時跟蹤技術是保證多波束測深系統實現高效率全覆蓋水下地形測量的核心技術，作者通過對多波束測深系統海底回波信號統計特性的研究，依據地形測量理論，並結合實際系統信號處理的技術特點和處理時序，提出了實現海底跟蹤控制的關鍵參數及計算方法，建立了基於中值濾波技術的海底地形實時跟蹤數學模型，並開發出實時地形跟蹤專家系統，該系統經多次海上實驗驗證表明：理論正確、方案可行，取得良好效果。
