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(chǔ)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。
based on the characteristic of system, the antenna is designed with one transmitter and two receivers and the localization principle of twsr is analyzed . target localization algorithm and error distribution computing method based on time-only-localization ( tol ) are proposed 同時根據(jù)系統(tǒng)特點,天線采用單發(fā)雙收方式,分析了穿墻探測雷達(dá)定位原理,提出了基于波達(dá)時間(tol)的目標(biāo)定位算法和誤差分布計算方法。
