DESCRIPTION |
The Goldstone Solar System Radar (GSSR) is the only
fully steerable radar in the world for high-resolution ranging and
imaging of planetary and small-body targets. The resulting data
provides both scientific and programmatic benefits, including
investigations of the Moon, planets, and other solar system bodies,
including near-Earth objects (NEOs). These studies provide images
and topography, and information on surface characteristics, shapes,
composition, orbits, rotations, and distribution of liquids or ice
on or below their surfaces. This investigation deals with raw data
consisting of complex base-band samples with real part or in-phase
(I) and the complex part or quadrature (Q), recorded from various
open loop receivers or recorders: Portable Fast Sampler (PFS),
GSSR Processing Computer (GPC) at various sample rates. Since
GSSR transmits right circular polarized (RCP) light, the
opposite-sense circular polarization (OCP, sometimes called
"polarized") is always left circular polarized (LCP) and the
same-sense circular polarization (SCP, sometimes called
"depolarized") is always RCP. The raw radar data can be used to
generate frequency spectra or delay-Doppler image maps, depending
on the transmitted waveform.
