Phased Arrays vs Aperture Synthesis
Great question! Phased arrays and aperture synthesis are closely related in radio astronomy and antenna engineering, but they’re not identical. Here’s a clear breakdown: Phased Arrays Aperture Synthesis Relationship ✅…
Normalising data produced by Easy Radio Astronomy Software Suite (ezRA) from multiple telescope systems to allow them to be combined to generate combined plots and maps.
This is very much a work in progress, so there isn’t a definitive answer from this post……. Andy Hi Ted, I asked ChatGPT to have a go at this and…
Formula for speed of light, and why it is a constant
What is the formula for the speed of light? Why is it considered a constant if there is a formula? Great question! Let’s unpack it step by step: 1. The…
Radio observation in hydrogen line (1420MHz)
SETI Horn of Plenty (Hydrogen Line Pyramidal Horn Design Antenna)
Dipole vs radio dish or horn
If your “two cables joined in the middle, held aloft on poles with a single feed down the centre” is a centre-fed wire dipole / inverted-V style tuned to 1420…

Normalising data files from multiple systems in ezRA
Ted Cline – N0RQV:secret ezCon command option …………. -ezConAntXTVTLevelL 1.3 -3.2 (multiply all AntXTVT sample values and add) Use per file (or batch files) to normnalise
How to take the signals from multiple antenna pairs and turn them into an actual sky image using Fourier transforms
Good question — you’re asking about the heart of radio interferometric imaging: how to take the signals from multiple antenna pairs and turn them into an actual sky image using…
Adding 2nd monopole onto cantenna to improve signal reception
Two monopoles at 90 degrees in cantenna One connects to splitter immediately Two connects via coax either 1/4 wavelength or 5/4 wavelength (more practical length = 26.5cm x 66% (velocity…
How do I normalise data from multiple radio telescope systems so I can combine them together?
How do I normalise data from multiple radio telescope systems so I can combine them together? Great question, Andrew. Here’s a practical, radio-astronomy-friendly playbook for putting multiple systems onto the…
