Abstract

Abstract:

To improve marine ecological field detection sensitivity and precision and lower detection limit, we analyze amplitudefrequency characteristics of interference signals and grasp their frequency domain characteristics for uniform amplitudefrequency property of seawater detection signal. Through the filtering of seawater detection signal, we get authentic monitoring data. The approach is stable and reliable, and can provide reference for development and application of marine ecological field detection sensors.

Key words: interference, signal detection, frequency domain
