Abstract
The application of the eigenstructure algorithm for estimating the Doppler (frequency shift) of wideband signals in noise is described. The problem is formulated in the context of a FM-CW radar where, the target range appears as a frequency shift which is then estimated. Our approach generalizes the well known results of Pisarenko for determining the Doppler (frequency shifts) of multiple harmonics in noise to the problem of estimating the frequency shifts of multiple wideband signals. Results of computer simulations that verify the performance of our proposed algorithm are also presented.
