Abstract
An algorithm for combined estimation of the frequency and its change rate by increasing chirp signal sampling is proposed. The algorithm allows sequential calculation of the frequency estimates taking into account the time correlation of errors of the initial phase difference measurements. The proposed method is computationally efficient, and the results tend to the minimum variance unbiased estimator as the input signal-to-noise ratio increases.
