HF/VHF spectrosopy code for the rx888mk2 direct-sampling receiver
rx2fits is an SDR code for the rx888mk2 direct-sampling receiver that streams spectral data with frequency up to 65 MHz to FITS files. This code is for the direct-sampling input of the receiver, which transmits real samples over USB3 at up to 130 MHz sample rate. rx2fits processes these samples to spectral intensities via a Fourier-transform poly-phase filter bank, which provides spectral resolution approaching the spectral bin width with good stop-band and adjacent-channel rejection. ...
Echoes is a radio spectral analysis software for SDR devices
Echoes it's a radio spectral analysis software for SDR devices, designed for meteor scattering purposes.
The older releases supported only RTL-SDR devices. They are very cheap SDR based on DVB-T TV tuner dongles based on Realtek's
RTL2832U chipset. Starting from 0.50 Echoes embeds SoapySDR allowing the support of many other SDRs.
Echoes doesn't demodulate neither decode any human-made signal.
GPU/MIC accelerated radio interferometric calibration program
SAGECal is a very fast, memory efficient and GPU accelerated radio interferometric calibration program. It can handle all source models including points, Gaussians and Shapelets. It can calibrate along hundreds of directions without running out of memory in almost real time. Intel Xeon Phi acceleration is also available. Distributed calibration using MPI and consensus optimization is enabled. Also tools to build/restore sky models are included.
GBTIDL provides offline data reduction for spectral line data from the GBT, a single dish radio telescope. Although the GBTIDL code is open source, running it requires you to have your own IDL license and base package.

The 'BandSystem' spectral analysis system is a rule-based system for the classification of mineral spectra. It consists of a preprocessor, a feature
extractor, and a rule-based system to identify minerals from infra-red reflectance spectra.
