Mini-RF Introduction
• Mini-RF is a NASA facility technology demonstration designed to demonstrate
new radar technology for future use in planetary resource mapping.
• The Mini-RF technology demonstration is a synthetic aperture radar which
consists of a fixed planar antenna and an electronics box, both mounted on
external spacecraft surfaces, a cable harness between the electronics box and the
antenna, and electrical interfaces to the spacecraft.
• The Mini-RF is sponsored by the Naval Air Warface Center/Weapons Division
(NAWC/WD), China Lake, California.

Mini-RF Requirements Traceability (1)
• Mini-RF Level 2 requirements are defined, and are traceable to a single Level 1
requirement defined in the Lunar Reconnaissance Orbiter (LRO) Requirements
Document, #ESMD-RLEP-0010.
– RLEP-LRO-P160 Technology Demonstration - The LRO shall accommodate the NAWC
provided Mini-RF device in order to provide the opportunity for demonstration of this
technology in the lunar orbital environment provided it does not increase the project cost, delay
the launch date, adversely impact the achievement of full mission success, or increase the
overall risk posture of the primary mission.
• Mini-RF requirements have been captured in a Requirements and Goals
Document and are in the process of submission to CM for release

Mini-RF Requirements Traceability (2)
• Key interface requirements are defined and captured in ICD’s for Mechanical,
Thermal, Electrical and Data interfaces
• Key operational requirements are defined and captured in the LRO Concept of
Operations Document
• Key performance assurance requirements are defined and captured in the RLEP
Mission Assurance Requirements (MAR) document, tailored for Mini-RF to
include only those areas that may adversely impact the achievement of full
mission success or increase the overall risk posture of the primary mission
• Key verification requirements are defined and captured in LRO Project Level
verification documents, including but not limited to:
– LRO Electrical Systems Specification
– LRO Mechanical Environments and Verification Requirements
– LRO Thermal Modeling Requirements Document
