AB: Frequency Modulated Continuous Wave (FMCW) measurements were made from the ground at one site (LSOS) during the 2002 campain and at 4 different sites during the 2003 CLPX campain. The system transmits a signal whose frequency varies linearly with time, and the transmitted and recieved signals are mixed before data aquisition to produce a signal which contains the differences in frequencies between the two signals. Measurements were made at C-, X-, and Ku-Band frequencies. Broadband (4GHz) measurements show a great deal of vertical stratigraphy within the snowpack, however narrowband measurements were also made to simulate airborne measurements. Experiments were also performed at different look angles, and metal reflectors were placed at various depths for calibration. All of the data collected during the NASA CLPX mission are summarized.
