| Abstract: | The problem of estimating the parameter of a linear frequency modulated signal embedded in additive noise is considered. Considering that the initial estimation of phase may be ambiguous, a modified algorithm for the estimation of the parameters of linear frequency modulated signal is proposed, which is based on phase unwrapping and polynomial fitting. Simulation experiments verify the effectiveness of the proposed modified algorithm. |
