AN ADAPTIVE NOISE CANCELLING SYSTEM TO ENHANCE SONAR RECEIVER PERFORMANCE -C31

The performance of sonar receivers on board a ship are degraded by mechanical noise. In order to improve the detection performance of the acoustic sensors (hydrophones), we have designed a local mechanical noise cancelling system using the Adaptive Noise Cancelling (ANC) approach with a single noise reference . The implementation was realized and validated on underwater acoustic signals with a PC-based Texas Instruments (TI(TM)) TMS320C31 floating-point digital signal processor (DSP) system.
