21cm Wavelength Circular_Patch_Feed Disk Director Yagi Antenna and 3D Graphic Software PROJECT
A Beginner's Guide to Antenna Fabrication, Reception, Recording, Software Processing, and Graphic Display of the 21 cm Wavelength Microwave Electro-Magnetic Emission Spectrum from Neutral Hydrogen ( Inter-Stellar Mass ) Clouds within our Galaxy : The Milky Way
THE GOAL : For a beginner ( high school or undergrad college student ) to have everything required for an operational Astronomical H Line Radio Telescope System Project available in One Repository, and offer intriguing 3D graphics as a motivation to undertake the task !
HARDWARE :
An Efficient Low_Noise Portable Economical 21cm Neutral Hydrogen Radio Telescope Antenna STUDENT EDITION
If built carefully to correct dimensions This antenna will have the same performance as the original
It is light enough to be mounted on a very low cost photo tripod
The intent of this Project is to provide directions to
fabricate a Student level 21cm Hydrogen Line
Radio Telescope able to be fully constructed with hand tools.
This antenna has excellent performance.
SOFTWARE :
Jamison Adcock has designed Java Software to Process
AirSpy SDR# Studio & Daniel Kaminski IF_Avg *.txt files by
Correcting the Spectra for Background Drift ,
Normalizing the Spectra to Cold Sky,
Converting the Spectra to a logarithmic dB Scale ( future alternate scalings )
Processing the Spectra files into *.csv Formats compatible with
Fumihiro Matsui Rinearn 2D and 2D Graphics packages
Output : Raw Data 2D/3D CSV, Frame to Frame Drift 2D CSV , 1pt & mx+b Drift Corrected and Normalized 2D/3D CSV : all Rinearn compatible
PLEASE NOTE : the Antenna can be used with Any Software | the Software can be used with Any Antenna
