對原海底檢波器二次定位軟體進行了全面細致的研究剖析，並對其相關原理進行了較深入的研究，利用visualc ~ （ + + ）與visualfortran語言混合編程技術，將原來基於unix工作站環境的海底檢波器二次定位軟體移植到了微機環境下的mswindows平臺上。So it is a comparatively simple step from locating the sea bottom to locating a shoal of fish
因此，從測定海底深度到測定魚群的位置這一進展相對較易。Different results specify that the first kind of cost function is sensitive to the mismatch of ocean depth and receiver location, but is insensitive to sound speed profile ' s % $ jai8x9 @ t $ m & z mismatch and has high accuracy of depth localizaion ; the second kind of cost fimction is insensitive to all three kinds of mismatch, but its resolution of depth is very low ln order to overcome the cost function ' s sensitivity to mismatch, improvemedt of the accuracy of time delay estimation and model calculation may be adopted, when both conditions are reached, the sensitivity wiil be greatly reduced and the resolution of range and depth will be improved at the same time
模擬結果表明，第一類代價函數對海底深度和基陣傾斜失配是敏感的，對聲速失配卻不敏感，並且能夠獲得較高的深度定位精度；第二類代價函數對三種失配都不敏感，只是深度解析度較低。為了克服代價函數對失配的敏感性，可採用提高時延估計精度和模型計算精度的方法。當兩個條件滿足時，敏感性得到極大的抑制並獲得了較高的距離和深度估計精度。The researches on re - positioning of ocean - bottom geophones after acquisition is a necessary part of the obc seismic exploration. this ocean - bottom geophone re - positioning system for ms windows in microcomputer environment is developed with vc + + 6. 0 and visual fortran 6. 0 co - programming technique, and it is based on the re - positioning software run in the unix workstation environment and financed by the national " 863 " sub - project " the research of three - component ocean - bottom geophone coordinate recognition and positioning methods ". the visibility of overall processes is realized
