Planetary Radar Astronomy with Ground-Based Astrophysical Assets

Abstract

Satisfying federal mandates requires continued and expanded support of planetary radar programs, upgrades to the facilities that host the planetary radar systems, and adequate communication between Congress and all relevant agencies that manage the facilities and the planetary radar programs. Continued research into improved radar transmitter technology and the use of phased array radars on interplanetary distance scales is warranted. Any breakdown of the planetary radar programs using single-dish astrophysical assets would be detrimental to planetary defense and small-body exploration on the timescale of the decadal survey.
