Under the Radar: Trials and Tribulations of Landing on Mars
TL;DR: In this paper, the Mars Phoenix mission requires a ground-sensing radar altimeter/velocimeter to meet touchdown velocity requirements during Phase C/D, the radar underwent a testing triptych: aerial testing, both captive carry and tethered drop tests (36 sorties, approx. 80 hrs), and Electronic Ground Support Equipment (EGSE) on the bench (500+ hrs).
