【 摘 要 】

Tow ship noise is a major problem plaguing the detection, classification, localization and tracking problems. It is a major contributor to towed array measurement uncertainties that can lead to large estimation errors in any form of signal processing problem aimed at extracting the weak target information. Many sonar-processing approaches ignore this problem relying on narrowband techniques to remove these undesirable interferences at the cost of precious signal-to-noise ratio (SNR). In this paper we address the idea of noise cancellation by formulating it in terms of a joint cancellation/detection problem. It is shown that the joint processor can be designed to perform in a broadband processing environment.
