| Abstract: | The passive localization technology based on the time-reversal mirror is a signal processing technology to implement spatial and temporal self-adaptation focusing for coherent sources and passive target location in the shallow sea,which can also position non-cooperative target.Four implementations for array passive time reversal mirror(APTRM) localization technology are proposed and the improved algorithms used to increase the processing gain,precision and robust of location are studied.The pool experiments... |
