HF ray path calculation is performed in order to identify possible ionospheric backscatter echo area for an HF radar at mid-latitude. The calculation is made on the basis of the R.M. Jones and J.J. Stephenson (U.S. Dept. of Commerce, OT Rep. 75-76, 1975) HF ray path tracing algorithm plus the IRI-2001 ionosphere model. It is shown that depending on the local time and geomagnetic activity, the possible ionospheric backscatter regions have different distributions. In any case the backscatter region is large enough, indicating the capability of a planned HF radar in Hokkaido (43.5°N, 143.6°E), Japan.
