Expanding the capabilities of the DPS ionosonde system.

Magnus, Lindsay Gerald (2001) Expanding the capabilities of the DPS ionosonde system. Masters thesis, Rhodes University.




The Digisonde Portable Sounder (DPS) is a low power pulse ionosonde capable of record-ing a wealth of scientic information about the ionosphere. The routine vertical incidence mode, that produces the scaled ionospheric parameters, only records limited Doppler and no precise angle of arrival (AoA) information. The drift mode produces precise scientic information but only limited range information. This thesis explains the operation of the DPS and then examines the drift data by rst showing the Doppler velocities (V )calculated for a xed frequency ionogram as well as the velocities calculated from an inter-esting ionospheric disturbance measured with a stepped frequency ionogram and second by illustrating the presence of a variation in the AoA of ionospheric echoes at sunrise. The conclusion of the thesis is that a drift vertical incidence mode be developed to allow the simultaneous measurement of the scaled ionospheric parameters and the precise AoA and full Doppler spectrum information.
