Research on Channel Impedance Parameters Dynamic Change Model of XCTD Profiler

Article Preview

Abstract:

In order to analyze low signal-to-noise rate (SNR) of data transmission while XCTD (Expendable Conductivity, Temperature, and Depth) probe drops at several kilometers underwater, a channel impedance parameters dynamic change model is established. The analysis showed that the greater distributed capacitance between parallel wires having the greater impact on SNR in deep-water channel, improvement of wire structure and material and reduce the distributed capacitance can improve the signal to noise ratio and transmission rate significantly, and that is providing a new way to solve the problem for XCTD signal transmission.
