Performance Evaluation of Energy Detectors

IEEE Transactions on Aerospace and Electronic Systems, 1978
The prediction of energy detector performance requires a complicated calculation or a tedious manipulation of nomograms. For a large time-bandwidth product WT, however, it is commonplace to use the formula (E/No) = d?WT to anticipate the required average input energy-to-noise spectral density ratio for a wanted signal detectability parameter d and thus

Energy Detectors and Complex Cells

2009
In preceding chapters, we considered only linear features. In this chapter, we introduce non-linear features. There is an infinite variety of different kinds of non-linearities that one might use for computing such features. We will consider a very basic form inspired by models previously used in computer vision and neuroscience. This approach is based

Energy Detectable by Radiation Detectors

Journal of the Optical Society of America, 1960
It is customary to evaluate the detecting ability of radiation detectors by stating the noise equivalent input power, or its reciprocal the detectivity, as a function of the modulation frequency. The statement is often given in terms of the detectivity D*, which is the reciprocal of the noise equivalent power referred to unit bandwidth and unit area ...

High Energy Neutron Detectors

1958
In the past few years, accelerators have produced neutrons of energy exceeding one billion (109) electron volts, and the next decade will see artificially produced particles of over twenty Bev. At present1, however, few neutron experiments have been carried out at energies above several hundred Mev, so the detection of neutrons with energy from 20 to ...

Detectors for Position and Energy Measurement

2007
As the primary ionization in semiconductors is proportional to the energy loss of the incident radiation or particle, most semiconductor detectors will provide the possibility of energy measurement if the readout electronics measures the signal charge.19 Position sensitivity may be obtained by creating a situation in which the signal charge is split ...
