本文利用電腦實高分析程式POLAN並藉由設定其參數：MODE, START和VALLEY將在Cleary, Alaska所測得的電離圖轉換為電子濃度之實高分布。然後，將此電子濃度之實高分布和Chatanika異調散射雷達的觀測資料相互比較。由此比較結果可以得知二者在電子濃度之實高分布上的差異，進而瞭解各種實高分析方法之優劣。

In this paper, a computer routine, POLAN, was used to convert an ionogram recorded at Cleary, Alaska to many electron density true height profiles by specifying various values of MODE,START and VALLEY parameters. These profiles are then compared with that measured by the Chatanika incoherent scatter radar. This comparison allows us to evaluate the difference of the electron density profiles respectively derived by using ionospheric sounding and incoherent backscatter techniques and to investigate the existing true height analysis methods.
