    Abstract
  • To realize short-range wireless signal transmission between the inside and outside of a sealed metal container filled with water, a method for underwater signal transmission using conductivity of water medium is proposed. Firstly, the theoretical model of signal transmission based on conductivity of water medium is analyzed. Then, a communication system based on conductivity of water medium is designed for underwater wireless signal transmission, and a test system is built to verify the reliability of this wireless signal transmission method. Under the testing condition, the electrodes can transmit signals without error at a transmission rate of 9.6 kbit/s when their spacing is within 40 cm. The proposed method and system can realize wireless transmission of data and instructions between the internal navigation control system and the external communication control system of launch tube, and ultimately improve test efficiency.
