 note = {The electron density profile in the lower and upper ionosphere was determined from the right and left handed circular polarized wave fields of the 40 kHz ground based signal observed by means of a rocket borne reciever. The determination of the electron density in the lower ionosphere was made under the condition for the values calculated by the full wave analysis to agree with the ob served values. While, the electron density in the upper ionosphere was determined from the attenuation ratio of the right handed circular polarized wave by using the method of WKB approximation., 資料番号: SA0124689000},
