A method is shown to estimate the position of a (single) radiation source fusing the data from a sodium iodide detector and a gyroscope while panning the detector. Based on geometry considerations, the search motion of a detector is modelled as angular panning and waving motions. Correlation of the sensor data stream from the an gyroscopical accelerometer with the count rate event data of the detector...
Scattering and attenuation have significant impact on the spectrum. For submersible nuclide identification devices, it is mandatory to still provide high quality identification results, even if the instrument is in the water. A technique is shown, to treat the effects of water scattering. This is done by combining the so-called dynamic derivative convolution method and a maximum-likelihood approach...
A stabilization concept based on a self-learning R-Tree index method is presented and demonstrated with measurements from a 1.5×1.5 cerium bromide detector. The concept uses a cognitive filter, a digital filter for nuclear signals that continuously updates itself to the current temperature by adjusting the filter components. The R-Tree combines the information from this cognitive filter together with...
A digital filter is presented that adapts automatically to the shape of a nuclear signal to stabilise against temperature induced peak shifting. The filter is called cognitive as it extracts the information about the exponential decays and determines the scintillation material intrinsically. The latter is done with a pole deconvolution approach.
