HFドップラによるEsの観測

抄録

The movement and structure of mid-latitude sporadic E layers are investigated using the HF Doppler technique. The three typical types of Doppler shifts are observed with the appearance of sporadic E, and the Doppler shifts expected from various types of moving sporadic E clouds are simulated using a microcomputer. The relative f_OE_S maps over Japan are described by processing the ionogram. Comparative study of their results is presented.
