| titleOfInvention | Time-domain-based method for tugboat interference suppression with wideband reverse beamforming |
| abstract | The invention discloses a time domain-based broadband reverse beam forming tugboat interference suppression method. Including: the tow line array signal is processed by matched filtering and broadband beamforming to obtain the initial frequency domain beam output, and after inverse Fourier transform, the initial time domain beam output is obtained; the azimuth and corresponding azimuth of the tugboat interference are detected from the frequency domain beam output In the time domain, the instantaneous power and local window signal level are used to detect the moment of interference and target aliasing, The interference time-domain beam output corresponding to the aliasing moment is reconstructed twice with the average power; the interference time-domain beam output after multiple rounds of iterative secondary reconstruction is subtracted from the initial time-domain beam output to obtain the time-domain beam output after the tugboat interference suppression . The invention effectively solves the problem that the target is also suppressed in the interference suppression, has good anti-multipath performance, and has strong application value in sonar engineering. |
