title = "The performance of time reversal beam-forming by linear array",
abstract = "The target orientation performance of time reversal by uniformed linear array is discussed over the ocean acoustic multi-path channel. Based on time reversal process, the signal detection system model is derived, and together with the self-adaptively beam-forming the algorithm is proposed. Comparing to the conventional array signal processing method, simulation result shows that time reversal could self-adaptively revise signal transmission delay due to multi-path channel, compensating the same phase correspond to each path wave-front, which reflects through target to each element of array, and strengthening receive signal absolute energy value which raises two orders of magnitude. Under conditions of the same max-SNR criterion whose level is 14.3dB, with the time reversal process combined with self-adaptively beam-forming method the ratio between main lobe and side lobe is improved by 2dB compared to conventional beam-forming. In a conclusion, the uniformed liner array under time reversal process improves the performance of target orientation compared to conventional beam-forming, especially under low signal to noise level",
