Abstract: A method and apparatus for extracting an ionospheric trace are provided. The trace extraction method includes: searching for a signal data having maximum strength among signal data displayed on an ionogram of the ionosphere; selecting the point where the signal data having maximum strength is placed as a first point; extracting the trace on the right side of the first point while increasing frequency of the signal data; and extracting the trace on the left side of the first point while decreasing the frequency.
