Abstract
A system and method for obtaining a Doppler frequency of a target are disclosed. A receiver receives a first plurality of samples of a first echo signal from the target and a second plurality of samples of a second echo signal from the target. The second plurality of samples is separated from the first plurality of samples by a time period. A phase shift is determined for the duration of the time period and the phase shift is applied to the second plurality of samples. The first plurality of samples is combined with the second plurality of samples to obtain combined samples, and the Doppler frequency for the target is obtained from the combined samples.
