bathymetric

Applying the information extracted from numerous hydrographic data of field trials collected by h / hcs - 017 , the first set of multi - beam swath bathymeter developed in china , a series of mosaic techniques have been carefully studied in this thesis , including digital terrain model building , statistical error analyzing , hydrographic data mosaicking as well as tides correction and projection of the earth coordinates . finally , standard digital sea - charts and three dimensional seafloor images are successfully developed that are consistent with hydrographic surveying principles 本文利用我國第一臺h hcs ? 017型條帶測深儀的測量數據進行拼圖技術的研究，主要研究的內容有：利用分帶原理對深度數據進行潮汐修正，得到瞬時海面的深度數據；對測深數據進行誤差分析處理，去除野值；將多波束數據進行坐標變換及投影轉換后構建數字地理模型，進而根據海道測量規范繪制標準海圖。

A conc1usion can be drawn that these algorithms has better preci si on and fitting for the multi - - beam swath bathymeter system better on the condition of 1arge beam ang1e , and can improve the precision of edge beams in non - - specu1ar seabed region 證明bdi和分裂孔徑相關法可以精確地對海底回波信號進行回波時延估計和方向估計，可提高非鏡向海底區域的邊緣波束的測量精度。

This paper also ana1yzes the sidescan mapping princip1e of the mu1ti - - beam bathymeter , and process the avai 1ab1e data with sidescan mapping method to achieve the sidescan imagery represented by the reverberation strength 本文還對多波束測深聲納側掃成像原理進行分析，利用現有的數據進行多波束側掃成像處理，形成表示海底反向散射信號強度的海圖。

Multi - beam swath bathymeter is a kind of newly developed advanced seafloor surveying equipment . it fits especially for mapping of large area of seafloor because of its high efficiency , high accuracy and fine terrain resolution 它是一種高測量效率、高測量精度、高分辨率的海底地形測量設備，特別適合大面積的掃海測量作業。

For the mu1ti - - beam swath bathymeter , array miniaturization wi th wide covering width has cause peop1e ' s more attention 對于多波束條帶測深儀來說，使基陣小型化而又達到大覆蓋要求的問題越來越引起人們的關注。
