Proposal Title: Radar Characterization of NEAs: Using Moderate Resolution Imaging, Astrom­
etry, and a Systematic Survey
ABSTRACT:
The purpose of this work is conduct the characterization of near­Earth asteroids (NEAs) accessible to the Arecibo
Observatory planetary radar during the 2016 calendar year, focusing on those objects expected to be of moderate­
to low­resolution (the higher­resolution objects are covered in a separate proposal). This e#ort will consist of three
approaches: (1) the performance of moderate­resolution imaging of 19 objects to improve their orbital solutions,
determine their radar reflectance properties, characterize their basic shape and morphologies, and look for
indications of a multiple component systems; (2) the performance of astrometric measurements (target range and
Doppler shift) on 2/3 of a collection of 39 objects, in order to improve their orbital solutions; and (3) the conduct
of monthly 8­hour (overnight) systematic observations, primarily for the purpose of performing either (1) or (2)
above on newly discovered objects that could not be included in this proposal.
