The sea gravimeters are widely applied to the reconnaissance of the sea oil and gas field, the perambulation of the sea terrestrial heat resource and the gravity passive navigation of underwater vehicles. The signal denosing method of the JSD-I/A quartz flexural gravitational sensor (JQFGR) is one key technology of the sea gravimeters, and the wavelet denosing method of JQFGR'S signal is researched in the paper. Firstly, the theory of wavelet transform is analyzed, and based on the signal singularity theory and the JQFGR's signal characteristic analysis, the united threshold method of wavelet transform is designed. Secondly, JSD-I/A quartz flexural gravitational sensor is fixed in the SCT-1 two axis rotational platform by the appropriative clamp, two teams of the JQFGS's signal are gathered. Thirdly, Daubechies wavelet and the united threshold method are used to process the JQFGS's signal. The mean square errors of the JQFGS's signal before experiment are 1.330994 × 10-9V and 1.23483 × 10-9V, and the mean square error of JQFGS's signal afte experiments are 1.069495× 10-9V and 0.955666 × 10-9V. The experiments results indicate that the Daubechies wavelet transform and the united threshold are effective to denoise the JQFGS's signal.
