| Abstract: | The underwater acoustic remote control system based on single chip processor is presented. The time correlation accumulating and pulse width discrimination are employed in the system. The experiments in Xiamen Harbor show that, under the low data rate transmission and the high S/N ratio, the system have excellent performances with the detection probability tending to 1 and the false alarm tending to 0. In addition, the design of soft anti interference and low power consumption are described. |
