Abstract:

      We develop a Michelson interference based ambient marine noise pressure monitoring system. We present a method of signal modulation and compensation. It  improves interference suppression capability and measurement accuracy. We also analyse the cause of error and error elimination method.

Key words: Michelson interference, sound pressure monitoring, tracking compensation
