The conventional direction finding method is to digitize the output of each sensor at the Nyquist sampling rate for the system bandwidth and use digital signal processing algorithms such as multiple signals classification (MUSIC) or maximum likelihood estimation (MLE) etc. In this paper, we exploit recent developments in compressed sensing (CS) to efficiently perform the direction finding. If the...
This article summarizes that the function of the predicting scope of the polygonal area of collapse in the mine goaf in WebGIS by VML with the algorithm of a parallel line on a broken line, for the current complexity of the algorithm and the limitation of the scope of application are not high, and accomplish the feature to show collapse range of mine goaf in WebGIS by VML. This kind of predicting...
In this paper, the problem of estimating the direction of arrival (DOA) in impulsive noise environments is considered. One possible way to model the impulsive noise is to introduce symmetric ??-stable (S??S) distribution. Robust co variation based MUSIC (ROC-MUSIC) and Fractional lower moment based MUSIC (FLOM-MUSIC) can be used to estimate the DOA under these conditions. But those methods require...
