Underwater Target Detection Method Based on Pole Distribution
2019 6th International Conference on Dependable Systems and Their Applications (DSA)(2020)
Abstract
As pole detection is generally used in radar, this paper proposes a new method for applying pole characteristics to underwater target detection. The methods of extended Prony and matrix pencil are used to extract the poles from the simulated target transient echoes whose parameters are changed, such as different frequencies and different signal to noise ratios. The influence of the factors above on the pole is analyzed, and the exact extraction of the pole and the dependence between these parameters are obtained. The original signal is fitted by using the matrix pencil method to extract the pole.
