On estimating parameters of a multi-component Chirp Model with equal chirp rates
Abhinek Shukla, Debasis Kundu, Amit Mitra +1
Multi-component chirp signal models with equal chirp rates appear in various radar applications, e.g., synthetic aperture radar, echo signal of a rapid mobile target, etc. Many sub…
On Consistency and Asymptotic Normality of Least Absolute Deviation Estimators for 2-dimensional Sinusoidal Model
Saptarshi Roy, Amit Mitra, N K Archak
Estimation of the parameters of a 2-dimensional sinusoidal model is a fundamental problem in digital signal processing and time series analysis. In this paper, we propose a robust…
Estimation methods for elementary chirp model parameters
Anjali Mittal, Rhythm Grover, Debasis Kundu +1
In this paper, we propose some estimation techniques to estimate the elementary chirp model parameters, which are encountered in sonar, radar, acoustics, and other areas. We derive…
A Computationally Efficient algorithm to estimate the Parameters of a Two-Dimensional Chirp Model with the product term
Abhinek Shukla, Rhythm Grover, Debasis Kundu +1
Chirp signal models and their generalizations have been used to model many natural and man-made phenomena in signal processing and time series literature. In recent times, several…
An efficient methodology to estimate the parameters of a two-dimensional chirp signal model
Rhythm Grover, Debasis Kundu, Amit Mitra
In various capacities of statistical signal processing two-dimensional (2-D) chirp models have been considered significantly, particularly in image processing to model gray-scal…
Asymptotic of Approximate Least Squares Estimators of Parameters Two-Dimensional Chirp Signal
Rhythm Grover, Debasis Kundu, Amit Mitra
In this paper, we address the problem of parameter estimation of a 2-D chirp model under the assumption that the errors are stationary. We extend the 2-D periodogram method for the…
