Interferometric Doppler imaging has become an integral part in radio
sounding of geospace plasmas. Doppler and angle of arrival measurements
have become important tools of ionospheric HF radio science. The state of
the art in HF sounding and automated ionogram interpretation for
ground-based and space applications is reviewed in this paper.
