Exploring the Feasibility cold-FET Calibration Standards to Improve Radiometric Measurements

Completed Technology Project

Project Introduction

This work seeks to further the development of the cold-FET calibration technology designed f next generation multi-band microwave instruments for space-based remote sensing applications. The short term goal of this IRAD is to quantify the plausibility of implementing and advancing cold-FETs, as tradeoffs exist between the technical-feasibility of this utility i.e., impact to the science
measurement, SWaP minimization, adaptability to current and future mission instruments, and the
nontechnical-feasibility such as cost, ease of implementation, and the level of effort (LOE) in advancing the
cold-FET towards a stand-alone cold-calibration standard, which is the long-term goal of this work.

Thus this study consists of two phases. Phase 1, the Research Study and Literature Review, will be conducted to determine the non technical-feasibility of this technology.  Phase 2 is an Empirical Research Study in cold-FET Calibration, embodies a creative approach to performing various calibration studies.
