This paper addresses the problem of estimating the instantaneous frequency (IF) of
multicomponent radar signals, which are assumed to be frequency-modulated (FM). The …

For the estimation of the frequency of a complex sinusoid, previous methods interpolate DFT
coefficients to obtain the frequency offset. Most of these interpolation methods can be …

Frequency estimation of a single complex exponential waveform is an important problem in
many fields. In this letter, a new frequency estimator for a complex exponential sine …

A computationally efficient method is proposed to estimate the instantaneous frequency of
multi-component signals for both mono-sensor and multi-sensor recordings. The proposed …

The estimation of time‐varying instantaneous frequency (IF) for monocomponent signals
with an incomplete set of samples is considered. A suitable time–frequency distribution …

The quasi-maximum likelihood (QML) algorithm has been extended to estimate the phase
parameters and the instantaneous frequency (IF) of the hyperbolic frequency modulated …

A two-stage technique for estimating hyperbolic frequency modulated (HFM) signal
parameters is proposed. In the first stage, coarse parameter estimations are performed …

Time–frequency (TF) distributions have been used for providing high‐resolution
representation in a large number of signal processing applications. However, high …

Instantaneous frequency (IF) estimation of non-stationary signals embedded in high noise is
addressed. When present, high noise represents a dominant error source in the IF …

Conventional time-varying filtering is inefficient for severely spoiled signals because it
requires discernible spectral content of the signal in time–frequency domain. Motivated by …
