深度定位 meaning in Chinese
depth localization
distance location
Examples
- This is confirmed to be effective by experiments . when problem of locating depth of defects is well settled , we establish the three - dimensional model of defect to calculate the three - dimensional coordinate of defect
在较好的解决了缺陷深度定位问题的基础上，本课题进一步建立了缺陷定位的三维数学模型，用来解决缺陷的三维坐标定位问题。 - 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
仿真结果表明，第一类代价函数对海底深度和基阵倾斜失配是敏感的，对声速失配却不敏感，并且能够获得较高的深度定位精度；第二类代价函数对三种失配都不敏感，只是深度分辨率较低。为了克服代价函数对失配的敏感性，可采用提高时延估计精度和模型计算精度的方法。当两个条件满足时，敏感性得到极大的抑制并获得了较高的距离和深度估计精度。
