Weighted least squares (WLS) localization algorithm for bistatic sonar was proposed by fusing the data of transmitter and receiver. The localizationprinciple and error of the algorithm were given.
The localizationprinciple 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.
Methods:Applying the principle of specific binding of antibody and antigen, make detection on accurate localization and qualitaliveness in tissues and cells.
