Radar Interference Blanking in Radio Astronomy using a

  title={Radar Interference Blanking in Radio Astronomy using a},
  author={Weizhen Dong and Brian D. Jeffs and J. Richard Fisher},
Radio astronomical observations of highly Doppler shifted spectral lines of neutral hydrogen and the hydroxyl molecule must often be made at frequencies allocated to pulsed air surveillance radar in the 1215-1350 MHz frequency range. The Green Bank telescope (GBT) and many other observatories must deal with these terrestrial signals. Even when strong radar fixed clutter echoes are removed, there are still weaker aircraft echoes present which can corrupt the data. We present an algorithm which… CONTINUE READING
