The new synthesis methodology for single-tone frequency estimation is proposed on the basis of the maximum likelihood (ML) method and autoregressive moving average (ARMA) models. The novel frequency estimator for the scenario with a strongly correlated interference and an additive white Gaussian noise is synthesized in a closed form. The assumption about a constant value of that interference allows...
The maximum a posteriori estimator of a single-tone signal frequency is synthesized. It is shown that this estimator has advantage over the simple maximum likelihood estimator that lies in its basis.
The improved approaches for a single source direction-of-arrival estimation in a far-field and near-field cases are proposed. In the far-field case the multichannel maximum likelihood frequency estimation along the uniform linear array is used for direct calculation of the single real spatial frequency. In the near-field case the same method is applied for short sub-arrays for retrieving a set of...
The present work offers the solution for a target speed estimation in two dimensional space by the distributed radar systems. The proposed method supposes initial separated estimation of speeds in all channels (as it is done in conventional systems) and further refined estimation of the target speed by the joined least squares optimization. It was shown that the refined estimation allows obtaining...
The present work is electronic offer the solution for single Doppler speed estimation by the colocated radar via multichannel frequency estimation of heterodyned signals. The maximum likelihood closed form estimator was synthesized using autoregressive moving average model of a sinewave. It was shown that the present method has advantage over estimators combined by averaging of multiple single-channel...
