Amateur Pulsar Radio Astronomy
The aim of this site is to encourage others to try detecting pulsars and to show that it may not be as difficult or as expensive as you may think.The pulsar plot of pulsar B0329+54 below was collected over a 2.5 hour period using a twin 17-element Yagi feeding a triple RTL SDR receiver.
B0329+54 Fold plot, at position 714 (0.5ms scale): 2hr10min record, SNR=4.4, rms noise ~ 0.006deg K
Test 1. Shows 1st half (red) + 2nd half (blue) data overlap correlation
Test 2. 2-period fold overlapped
Test 3. 3-band fold overlapped (red-609MHz, blue-611MHz, green-613MHz; 2.4MHz BW)
Test 4. Pulse shape/Width comparison with 25m dish pulse (blue) by M Klaassen
Test 5. Scintillation characteristic
Test 6a. Period search - increase by 1ppm, calculated -7bin shift confirmed
Test 6b. Period search - decrease by 1ppm, calculated +7bin shift confirmed
Test 7. Dispersion check - factor 2 over-dispersed; pulse shift/spread and amplitude reduction confirmed
The Ultimate Test. Positive and negative stepped dispersion of a real pulsar pulse confirmed
Integrated pulsar plot of seven days observations - Final Signal-to-Noise ratio = 8.7 (Contributions - 3.3, 3.4, 4.9, 3.0, 3.1, 4.0, 4.5)

Note: Due to excessive demand and pdf-liking bots my web page has been archived twice.
For bona-fide users I have had to modify the pdf document links by adding a space before the .pdf extension.
