Considering the low performance of accuracy and convergence of the traditional Singer algorithms for maneuvering detection, this paper proposed an improved Singer algorithm which deals with the adjustments of the matrix of the process noise covariance and changes of the filtering gain according to the average attenuation of innovation and the filtering value of acceleration. The new algorithm can...
When suing the multiple signal classification (MUSIC) direction finding algorithm based on uniform linear array, the estimation of the real arrival direction may be interfered due to the occurrence of the spurious spectral peak if the ratio of the element spacing to wavelength is more than 0.5. The available methods of eliminating spurious spectral peak are mainly suitable for active direction finding...
The ALICE calorimeters PHOS and EMCal are based on Avalanche Photo-Diode (APD) photosensors with Charge Sensitive Preamplifiers (CSP) for readout of the scintillating elements. The amplified signals are read out via 32-channel shaper/digitizer front-end electronics (FEE) with 14-bit effective dynamic range. The electronics is based on second order shapers with dual gain for each channel, getting digitized...
This paper presents a structure-oriented Gaussian (SOG) filter for reducing noise in 3D reflection seismic data while preserving relevant details such as structural and stratigraphic discontinuities and lateral heterogeneity. The Gaussian kernel is anisotropically constructed based on two confidence measures, both of which take into account the regularity of the local seismic structures. So that,...
