Pulse Ranging Method Based on Active Virtual Time Reversal in Underwater Multi-Path Channel

Pulse Ranging Method Based on Active Virtual Time Reversal in Underwater Multi-Path Channel

Aiming at improving the accuracy of pulse ranging measurement in underwater multi-path environment, this paper proposes a novel pulse ranging algorithm based on active virtual time reversal (AVTR). By using the focusing characteristics of AVTR, the received signal can be focused at the receiving end...

By using the focusing characteristics of AVTR, the received signal can be focused at the receiving end, which eliminates the negative influence of multiple pseudo-peaks. In order to extract the received signal, we propose an energy-based adaptive windowed method which preserves the signal focus peak while truncates the side peak component. Numerical simulations are provided and outfield experiments are conducted. The results demonstrate the effectiveness of the proposed method comparing with correlation-based method.https://www.mdpi.com/2077-1312/8/11/883underwater acousticmulti-pathpulse rangingactive virtual time reversal
