英文摘要：

This paper presents and realizes a time domain detecting method to acquire HF Doppler frequency shift with high precision in real time by using echo s phase measurement and processing arithmetic aimed at the shortcoming of frequency domain detecting method.Experimental results reveal that the time domain detecting method can acquire HF Doppler frequency shift parameter with high precision in real time and it can fully meet the demand in ionospheric small-scale disturbance observation and research.
