Abstract As a very important and widely used signal analysis and processing method, spectrum estimation
technology has been the focus and hot spot in the field of underwater acoustic signal processing. In this paper,
the fast orthogonal search algorithm is applied to the spectrum estimation of underwater acoustic signals. The
parameters are searched by implicit orthogonal method to estimate the frequency, amplitude and phase of
the signal. The simulation and experimental data processing results show that compared with the traditional
spectral estimation method, this method can estimate many parameters of underwater acoustic signal stably
and accurately, and obtain the spectral estimation results with high frequency resolution.
Key words Fast orthogonal search, Spectral estimation, High resolution
