Useful software and system descriptions related to pulsar detection.

NOTE: the software links provided here are external links - naturally it is *your* responsibility to scan any executable code downloaded with *your* virus-checker before execution.

If you decide not to accept this responsibility then don't download them.


Unfortunately a major task for successful pulsar detection is the use of specialised software.  For the professional working at a professional observatory this software is already installed for the most part.  The amateur, however, must set about installing their own set of software and assemble their own processing systems.

Fortunately a lot of good work has been done by amateurs towards this end.  There are a number of solutions available. Which solution is the most appropriate for the reader will depend on the reader's previous experience and preference.

Follow the links below and choose a suitable solution.

Hannes Fasching (OE5JFL) : Pulsars – How To Detect (TBD)

Marcus Leech : pulsar_filterbank

A Gnu Radio flow-graph for producing raw filterbank files from a live SDR It produces 16-bit binary outputs, arranged from lowest to highest frequency in the filterbank output. The code automatically determines suitable filterbank sizes and output rates. A header file is produced that gives the calculated rates, etc.

Mario Natali (I0NAA) : MURMUR

A program that predicts if a receiving set-up is potentially able to detect pulsars. The program has also several other functions to assist in planning observations.  Mario is also developing a program (in beta) that reads the .bestprofile files generated by the PREPFOLD program, calculates the S/N and shows all parameters.

Nando Pellegrini (I1NDP) : B200 System Pulsar Observation Software for the Amateur

The system allows the recording on disk from SDR receivers and transform the output into a format compatible with the “presto/tempo” pulsar search suite. The B200_system was originally designed to be used with the Ettus Research B200mini SDR, but the use of the Airspy has now been added.
