  1. Signal Processing Ambitions for DSN Radio Astronomy Tom Kuiper JPL - Caltech NASA DSN Radio Astronomy

  2. NASA DSN Radio AstronomyDSN Station Locations

  3. NASA DSN Radio AstronomyGoldstone – Madrid - Canberra

  4. Radio Astronomy Receivers 18.0 – 26.5 GHz (70-m antennas)‏ 39 – 50 GHz (Madrid 34-m)‏ 31 – 34 GHz (Goldstone 34-m)‏ NASA DSN Radio Astronomy • Standard Receivers • 1.6 – 1.7 GHz (70-m antennas)‏ • 2.2 – 2.3 GHz • 8.2 – 8.6 GHz • 31.5 – 32.5 GHz (not 70-m antennas)‏

  5. NASA DSN Radio Astronomy18-26 GHz Receiver Concept

  6. NASA DSN Radio Astronomy • Data recorders (Standard DSN equipment)‏ • MkV VLBI (500 MHz BW, post real-time processing)‏ • VLBI Science Receivers ( 4x16 MHz BW, near real-time software PFB, FFT, AC)‏ • Autocorrelators (Spaceborne)‏ • Canberra (400 MHz, 4096 ch)‏ • Madrid (500 MHz, 1024 ch)‏ • Goldstone (500 MHz, 1024 ch)‏

  7. NASA DSN Radio Astronomy Current Research • Extragalactic water masers (wide bandwidth, high resolution, [two polarizations])‏ • H20, NH3 (three lines), CCS [,C3H2] in star forming regions • CCS 11 GHz Zeeman effect in pre-protostellar clouds • VLBI • SETI

  8. NASA DSN Radio AstronomyFuture Capability • Search for extragalactic water masers: two polarization beamswitching (four IFs) with 8192 ch over 400 MHz • Search for RRATs and isolated bursts (400 MHz BW real-time de-dispersion and capture)‏ • Giant nanosecond pulses between 18 and 26 GHz, full Stokes (de-dispersion and capture)‏ • Monitor Mars electrostatic microdischarges

  9. NASA DSN Radio AstronomySignal Processing Roadmap • 08Q4 • ROACH with 1 ADC prototype development • Repair and deploy 128M ch SETI spectrometer • 09Q1-2 • Deploy and field test prototype at Goldstone • 09Q3-4 • Deploy one ROACH to each station • 10Q1 ff .....
