Abstract:
In order to eliminate the multipath errors existing in static short-baseline applications, a novel de-noising method based on a singular spectrum analysis(named as DSSA)is introduced to extract multipath signals. The multipath error is extracted from the double difference(DD)residuals by DSSA and then applied to the correct multipath error in subsequent measurements based on the correlation among adjacent epochs. Methods based on discrete wavelet transform(DWT)and stationary wavelet transform(SWT)are introduced as comparisons of DSSA based on analysis of a simulated signal. Real baseline residuals are tested to verify different extract methods. Results show that compared with the SWT, the DSSA improves the root mean square(RMS)of the residual by 48.6% and achieves a time reduction of 75.3%.
