| dc.description.abstract | In this report the performance of a high-resolution beamformer is compared to that of the conventional | |
| dc.description.abstract | beamformer in detecting a low-level narrow-band signal in the vicinity of a number of high-level noise | |
| dc.description.abstract | sources. This scenario may arise in areas where shipping noise is predominant, the acoustic field | |
| dc.description.abstract | being dominated to a large part by the contributions of individual ships. In this study a comparative | |
| dc.description.abstract | detection performance test is conducted with a simulated source embedded in a real ship-induced | |
| dc.description.abstract | noise field and received on a 64-element towed array. The results shown suggest that in such noise | |
| dc.description.abstract | fields the detection performance of the conventional planewave beamformer is greatly reduced due to | |
| dc.description.abstract | a lack of resolving power. High-resolution techniques may overcome this difficulty and a detection | |
| dc.description.abstract | improvement of 5% to 20% is obtained in the detection of a low-level target in the frequency range | |
| dc.description.abstract | below 250 Hz. When the signal-to-noise ratio increases the performance of both algorithms is | |
| dc.description.abstract | comparable | |
