The Goldstone Solar System Radar is part of the JPL/NASA Deep Space Network.


The Goldstone main antenna, DSS14, is a fully steerable, 70-meter, parabolic reflector with horn feeds. Its 500-kilowatt transmitter is the world's most powerful at X-band (8560 MHz, 3.5-cm).


Bistatic experiments using DSS-14 transmissions and reception of echoes at DSS-13, a 34-m antenna 22 km away, have been conducted on several very close targets.


Bistatic experiments employing transmission from DSS-14 and reception of echoes at the 27-antenna Very Large Array ( VLA) in New Mexico have synthesized a beamwidth as small as 0.24 seconds of arc, vs. 2 minutes of arc for single-dish observations with Arecibo or Goldstone. In coming years, bistatic observations between Arecibo and Goldstone, or using transmission from Arecibo or Goldstone and reception at the 100-m Greenbank Telescope (GBT), now under construction, should prove advantageous for outer-planet satellites and nearby asteroids and comets. Test observations using transmission from Goldstone or Arecibo and interferometric reception with the 10-antenna Very Long Baseline Array (VLBA) are planned for 1998, and in principle can produce resolutions near a milliarcsecond.


Click here for plots of predictions of the single-date signal-to-noise ratio (SNR) as a function of asteroid size, distance, and declination, for Arecibo and Goldstone. The SNR, which increases as the square root of the number of dates, is comparable to the number of pixels that images can place on a target.
