Application of New Ultraviolet Television Detectors in an Astronomical Satellite

1972
Publisher Summary This chapter presents the application of ultraviolet television detectors in an astronomical satellite. The scientific purpose of small astronomical satellite-D (SAS-D) is the spectroscopic study of a wide range of astronomical sources in the spectral region between 115 and 320 nm.

The New γ-CFAR Detector For Astronomical Image Processing

1997
In this paper, we propose a new constant false alarm rate (CFAR) detector based on a family of gamma kernels which provide the ability to change the scale and shape of a stencil that models the local area in an image. This new detector is called the CFAR detector. The scale and shape can be selected adaptively after training in such a way so as to give

Construction and operation of a cloud detector to assist astronomical observations

2003
The Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE) is a ground based gamma ray telescope which studies active galatic nuclei (AGNs). As a ground based experiment, data quality is directly related to atmospheric conditions. This thesis describes the process of verifying the reliability of astronomical weather predictions made by the ...

Investigation of a resistive anode detector for astronomical spectroscopy

1986
A large format two dimensional photon counting detector has been evaluated as a detector for astronomical spectroscopy. The design comprises an 320 photocathode, a tandem MCP gain stage and a circular arc terminated resisitive anode to provide pOSitional coordinates of detected events.
