Of the two completed SDR receiver (hardware) designs based on the RASDR concept (wide-bandwidth, Windows-compatible, documented SDR for Radio Astronomy), only RASDR4 is now marketed.
Identification and accurate spectral characterization of a narrow L-band spectral feature from a celestial source is a necessary first step in showing the importance of a Doppler (velocityind...
The Radio Astronomy Software Defined Receiver (RASDR) is a system that provides a versatile Software-Defined Receiver (SDR) that is optimized for Radio Astronomy. RASDR2 is the current hardwa...
Decades of experimental studies led physicist James Clerk Maxwell to formulate the theoretical foundations of electromagnetic energy in 1862. Thirty years later, another physicist, Henrich He...
An update of the RASDR project will be presented. The paper demonstrates Windows control of the RASDR system. User-provided data specifies center frequency, bandwidth, and some initial values...
The RASDR design team is releasing a software-defined receiver (SDR) for radio astronomy called RASDR2. The receiver consists of two high-density circuit boards -- a wide-band femtocell chip ...
