The localization principle of bistatic sonar is given and the gdop ( geometry dilution of precision ) which used in bistatic radar for describing the localization error has been cited in bistatic sonar 在對雙基地聲吶定位原理和定位誤差分析的基礎上,提出了用定位精度的幾何解釋( gdop )來表征雙基地聲吶定位誤差的方法。
These analysis is based on a great deal of test . some conclusion is : geometry dilution of precision and the number of satellites can be used to pick out some abnormal points . to group the data according to the vertical dilution of precision can also pick out some abnormal points 通過對ag132大量實驗和精度分析,提出了可以通過gps信號接收時的幾何精度因子、衛(wèi)星個數(shù)等首先剔除浙江大學博士學位論文摘要一批gps信號中的異常值,然后可以通過垂向的按幾何精度因子分組判別法剔除一些異常值。
