Microwave radiometers have recently demonstrated a new capability by detecting internal waves in the atmospheric boundary layer and localizing their altitude. Varying the intersection height of a narrow antenna beam with that of a wide vertically pointing antenna beam allowed determination of the wave altitudes. The ground‐based radiometers were located at San Diego where, in an experiment in May‐June 1975, the Naval Electronics Laboratory Center provided "atmospheric‐truth" for comparison to the radiometer data obtained by the Naval Research Laboratory. Preliminary results showed cases of correspondence between the signals of the passive radiometers and the active FM‐CW radar and acoustic sounder systems. Examples included internal wave trains up to an hour in length.
