Because of the separable resource and receiver, Multistatic sonar have many special character in underwater target detect and localization.
多基地声呐由于其收发设备分置，因而在水下目标的检测和定位方面，具有很多独特的优点。

Movement compensation is the key technique in synthetic aperture sonar(SAS) imaging, and it is normally realized in SAS system by the cross correlation of the raw echo data of multiple-receiver.
Weighted least squares (WLS) localization algorithm for bistatic sonar was proposed by fusing the data of transmitter and receiver. The localization principle and error of the algorithm were given.
