So to be able to detect pulsar in reasonable observation time, the minimum gain of the antenna should be at least 14dB at 400 MHz. I choose a linear polarization for the antenna because it is the most simple configuration. The choice of antenna type is guided by several factors: budget and construction time, compactness, […]
Step to the neutron stars 3. B0329+54
In this project, I aim to detect only one pulsar - B0329 + 54. It is the most powerful radio pulsar in the Northern Hemisphere. It is located in the constellation Camelopardalis ( Girafe ) and should be easy to find. Data from ATNF Pulsar Catalogue Name B0329+54 PSRJ J0332+5434 Right Ascension 03:32:59.368 Declination +54:34:43.57 […]
Step to the neutron stars 2. Radiometer equation
Let us consider a source of unpolarized flux density . This flux is collected by a telescope with an effective area of , where is the geometric area of the telescope and is the efficiency of the telescope. Since the contribution of each of the polarization is half in the total flux, so the power […]
Step to the neutron stars 1. Intro
This year I had started the most complicated project which I had ever done -- radiotelescope. First, I saw the idea of home radiotelescope in the book Wojciechowcki from 1977 (actually quite an exciting book with many brilliant ideas). Later I saw the efforts to build it at the Kyiv Astro club forum. But what I'm […]
MAX10 development board
I was thinking about the new development board in 2015. That year, on market, appears new MAX10 FPGA's. I bought them, but I didn't use since that time. First I thought about numerous toys on it: Ethernet, HDMI, USB, SDRAM... But soon I realize that I don't have enough FPGA legs to control it all. […]
