| Abstract: | Due to favorable tolerance of environment and focusing of energy in time reversal,a single monostatic trans-ducer with active time reversal signal can be used to detect targets of low signal to noise ratio.With the acoustic multi-path model based on classic ray theory,the feasibility of active TR signal detection is conducted theoretically.Through the detailed analysis of the active TR processing gain of a single monostatic transducer,the approximately proportional relationship between processing gain and t... |
