A Field Programmable Gate Array Spectrometer for Radio Astronomy
نویسندگان
چکیده
We describe the technological concept and the first–light results of a 1024-channel spectrometer based on field programmable gate array (FPGA) hardware. This spectrometer is the prototype for the seven beam L-band receiver to be installed at the Effelsberg 100-m telescope in autumn 2005. Using " of-the-shelf " hardware and software products, we designed and constructed an extremely flexible Fast-Fourier-Transform (FFT) spectrometer with unprecedented sensitivity and dynamic range, which can be considered prototypical for spectrometer development in future radio astronomy.

متن کاملAccelerating a Software Radio Astronomy Correlator using FPGA co-processors
Introduction This poster presents and characterises our work on accelerating a software radio astronomy correlator using reconfigurable computing (RC) hardware. Radio astronomy correlation is an embarrassingly parallel signal processing application, which is used heavily in radio astronomy for imaging and other astronomical measurements. Radio astronomy correlators typically operate on huge dat...
