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。The effects of waves transformation, refraction, diffration, reflection and breaking are all due to the depth of water, varying topography, bottom friction, obstacles and current as waves proceed from offshore to near shore regions. some basic parameters which are relevant to the cost of buildings as well as the type of structures are determined by the wave factors since these projects are placed in near shore area, so it is of great importance to study the regularity of wave transforming
外海波浪傳入近岸淺水區受水深、地形、底摩擦、障礙物以及水流等因素的影響，會發生變形、折射、繞射、反射和破碎等各種現象，然而大部分海洋及海岸工程位於近岸地區，該地區的波浪要素將是確定工程造價、建築物型式等最基本的參數，因此研究近岸地區波浪的變化規律具有重要意義。In mfi, the thesis uses the bottom reflection phase shift as the cost function and the modal wave number as input data. also, it makes errors analysis by the statistical distribution between data errors and parameter errors. there are some new ideas in it
論文在使用匹配場反演方法反演海底參數中以海底反射相移曲線作為代價函數，模式波數作為輸入數據，同時利用統計分佈進行誤差分析，具有一定的新意。In the aspect of detection and high precision estimation of seafloor backscattering, algorithms of fast convergence of energy center and correlation of eigen - replica were developed. also studded were processing methods of weighted mean time ( wmt ) and bearing direction indicator ( bdi ) based on fft beam forming as well as high precision detection and estimation of time of arrival ( toa ) and direction of arrival ( doa ) using split beams phase difference detection technique
圍繞海底反向散射信號的高精度檢測和估計技術，開發了快速能量中心收斂演算法和特徵模型相關演算法，研究了基於fft波束形成的加權時間平均與方位指示處理方法，並討論了利用分離波束相位差檢測技術的海底反向散射信號到達時間（ toa ）和到達方向（ doa ）的高精度檢測與估計方法。分享友人
