摘要：
The target detection and localization in uncertain environment with robust time reversal(TR) technique was investigated.TR is a physical process as well as a method of signal processing.Therefore,it is natural to perform beamforming via TR,i.e.,TR beamforming (TRBF).To reduce the effects of environmental uncertainty on TR spatio-temporal focusing, transmitting TRBF with modeled instead of physical probe source was studied and robust minimum-variance receiving TRBF with diagonal loading was put forward.Both of them were applied to the detection and distance estimation of the target,which was dealt with in a waveguide experiment.The experimental results show the validity of the methods in uncertain environment.
