    • Radio science measurements of atmospheric refractivity with Mars Global Surveyor 

      Cahoy, Kerri; Hinson, David; Tyler, G. Leonard (American Geophysical Union, 2006-05-20)
      Radio occultation experiments with Mars Global Surveyor measure the refractive index of the Martian atmosphere from the surface to ~250 km in geopotential height. Refractivity is proportional to neutral density at low ...

    • Communication satellite power amplifiers: current and future SSPA and TWTA technologies 

      Aniceto, Raichelle; Cahoy, Kerri; Lohmeyer, Whitney (Wiley, 2016-04)
      This study captures the state of current satellite transponder technology, specifically, solid-state power amplifiers (SSPAs) and traveling wave tube amplifiers (TWTAs), and describes expected future advances, including ...

    • Radiometer Calibration Using Colocated GPS Radio Occultation Measurements 

      Cahoy, K. L.; Blackwell, W. J.; Bishop, R.; Cohen, B.; Crail, C.; e.a. (Institute of Electrical and Electronics Engineers, 2014-10)
      We present a new high-fidelity method of calibrating a cross-track scanning microwave radiometer using Global Positioning System (GPS) radio occultation (GPSRO) measurements. The radiometer and GPSRO receiver periodically ...
