- Abstract
- The oblique ionospheric sounding technique using HF radar have some advantages in terms of that the obliquely sounded HF signal have the abilities to monitor the ionosphere of some places where it is not deployed vertical sounder between transmitter and receiver and of course, to vertically detect the ionosphere of area where it is deployed itself. It allows obtaining more information of ionosphere, such as critical frequency, vertical height and electron density, MUF (maximum usable frequency) over a wider area with no additional ionosonde. We present the results of experimental studies of oblique sounding for research purpose between Jeju and Icheon stations in Korea which are about 420km apart. The algorithm we proposed calculates the electron density profiles in ionosphere which considered the incidence angle, the Doppler frequency, the influence of traveling ionospheric disturbances (TIDs), the multipath propagation, and the error probability. Adaptability for obliquely sounded HF signal to ionosphere are mainly focused.
