A Computationally Efficient algorithm to estimate the Parameters of a Two-Dimensional Chirp Model with the product term
含乘积项二维啁啾模型参数估计的计算高效算法
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 methods have been proposed for parameter estimation of these models. These methods however are either statistically sub-optimal or computationally burdensome, specially for two dimensional (2D) chirp models. In this paper, we consider the problem of parameter estimation of 2D chirp models and…
