Estimate the Parameters of Motion Target Used of Interference Spectrum on OMAP

With the rapid progress of the silent technology, the radiated noise of ships and submarines is getting lower and lower, but its low frequency component is difficult to eliminate. This paper concerns the low frequency vector sound field interference structure and combines STFT with HOUGH to deal with the low frequency of vector sound field broadband spectrum, this method can be used to estimate the moving target’s parameters, and this algorithm is transplanted to OMAP.
