Detecting Doppler frequency shifts from ionospheric high‐frequency echoes is an important way to study ionospheric disturbances. This paper presents and realizes a new mode for observation of ionospheric disturbances using a combination of coded pulses and echo phase measurement analysis in ionospheric vertical sounding based on the Canadian Advanced Digital Ionosonde (CADI) platform. Experimental results show that the newly developed mode for observation of ionospheric disturbances on CADI can acquire accurate Doppler ionogram (Dopplionogram) and obtain temporal and spatial variations of the velocity of ionospheric disturbances in real time so that it has essential value in observation and research of ionospheric disturbances. The application of the new mode for observation of ionospheric disturbances in ionospheric vertical sounding opens up a new, effective way by which much more ionospheric information can be acquired with existing common ionospheric sounding instruments.
