The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

The Microwave Imager (MWI) on the Weather System Follow-on – Microwave (WSF-M) satellite contains fully polarimetric channels at 10.85, 18.85, and 36.75 GHz. Like its predecessor WindSat, fully polarimetric channels provide observations of the ocean wind vectors due to the polarimetric dependency of ocean emissivity on both wind speed and direction. Like dual-polarization radiometers, the MWI measures both vertical polarization (v-pol) and horizontal polarization (h-pol) through the antenna. The MWI computes the other polarization states (3rd and 4th Stokes) by digitally correlating the v-pol and h-pol inputs.

For a dual-polarization conical scanning radiometer, the sensor calibration reduces to a handful …

Towards Picowatt Optical Power Measurement Using A Frequency Programmable Josephson Voltage Standard, Malcolm White, N. Tomlin, A. Rufenacht, A. Fox, J. Lehman, S. Benz, A. Gamouras, D. Dalacu, R. Williams

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

We directly measure the electrical substitution power of a cryogenic radiant power detector by use of a frequency-programmable Josephson voltage standard (FPJVS). We demonstrate the practicality of the technique by using an FPJVS to set the voltage across the resistive heater of a standard NIST cryogenic radiometric detector. The FPJVS dc bias current source supplies dc current to the resistive heater. In this demonstration, the uncertainty of the substituted electrical power is limited by the uncertainty of the electrical heater resistance measurement at 4 K. We estimate this uncertainty to be 10 ppm. We aim to develop the technique to …
