Low-quality SNR data usually cause abnormal phases in the fitting of non-linear least squares (LLS) algorithms. This is not conducive to the effective use of multi-satellite phases. In this paper, we proposed a retrieval method of SM based on multi-satellite combinations considering detection...

The importance of text mining stems from the availability of huge volumes of text databases holding a wealth of valuable information that needs to be mined. Text mining is a coarse area encompassing many finer branches one of which is text categorisation or text classification. Text...
