RF Beacon Ground Stations Dispersive-Phase/Differential Doppler Measurement System

In support of the SECEDE II barium release RF Beacon Test Series, Electrac, Inc., designed, fabricated, installed and operated on site, four Dispersive-PhaseDifferential Doppler Measurement Systems. The experiments primary purpose was to further the diagnostic objective of obtaining descriptive information about the barium ions produced in the test series. The cloud parameter to be measured was the integrated electron density along a line-of- sight as a function of the lines cloud penetration position. Of prime interest were integrated density striations. The report describes the measurement system, including design criteria and final configuration of the four systems as installed in the field.
