SETI Signal Processing and Radio Astronomy Applications at Arecibo, Greenbank, CARMA and the ATA

Our SERENDIP (Search for Extraterrestrial Radio Emissions from Nearby Developed Intelligent Populations) project seeks to detect anomalous radio signals by spectrally decomposing Arecibo telescope data. Based on reconfigurable FPGA technology, our latest spectrometer hardware is seeing wide use within the radio astronomy community--proving the feasibility of developing general-purpose signal processing hardware. We have developed platform-independent parameterizable, customizable algorithms for polyphase filtering, correlation, digital mixing, and filtering. These libraries are valuable for the next-generation spectrometers we are developing with the Berkeley Wireless Research Center (BWRC) for general use, particularly in the field of antenna correlation.
