Abstract: In an approach to extracting satellite Doppler curves from waterfall spectrograms, a system includes one or more computer processors; one or more non-transitory computer readable storage media; and program instructions stored on the one or more non-transitory computer readable storage media for execution by at least one of the one or more computer processors. The stored program instructions include instructions to receive satellite data; remove a first noise from the satellite data; agglomerate the satellite data into one or more clusters using adaptive clustering; fit a Doppler curve model to each cluster of the one or more clusters; remove noise clusters from the one or more clusters based on a second noise; and determine one or more orbital elements of a satellite for each remaining cluster of the one or more clusters.
