A target parameter estimation algorithm for integration of radar and communication based on orthogonal time frequency space

open access: yesIET Radar, Sonar & Navigation, 2023
Orthogonal time frequency space (OTFS) is a new method technique that supports reliable information transmission in a strong Doppler environment. Aiming at the radar target parameter estimation problem of integration of radar and communication (IRC ...

ACD estimation of the S parameter revisited [PDF]

open access: yes, 1997
The analytic continuation by duality (ACD) technique has been used to estimate the electroweak S parameter in technicolor models. In this letter, we investigate the reliability of this method by applying it to some toy models with known spectra.

Progress in Accurate Chemical Kinetic Modeling, Simulations, and Parameter Estimation for Heterogeneous Catalysis

open access: yesACS Catalysis, 2019
Chemical kinetic modeling in heterogeneous catalysis is advancing in its ability to provide qualitatively or even quantitatively accurate prediction of real-world behavior because of new advances in the physical and chemical representations of catalytic ...

A systematic method of parameterisation estimation using data assimilation

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2016
In numerical weather prediction, parameterisations are used to simulate missing physics in the model. These can be due to a lack of scientific understanding or a lack of computing power available to address all the known physical processes ...

Simultaneous estimation of land surface scheme states and parameters using the ensemble Kalman filter: identical twin experiments [PDF]

open access: yesHydrology and Earth System Sciences, 2011
The performance of the ensemble Kalman filter (EnKF) in soil moisture assimilation applications is investigated in the context of simultaneous state-parameter estimation in the presence of uncertainties from model parameters, soil moisture initial ...

Constrained Parameter Estimation for a Mechanistic Kinetic Model of Cobalt–Hydrogen Electrochemical Competition during a Cobalt Removal Process

open access: yesEntropy, 2021
A mechanistic kinetic model of cobalt–hydrogen electrochemical competition for the cobalt removal process in zinc hydrometallurgical was proposed. In addition, to overcome the parameter estimation difficulties arising from the model nonlinearities and ...

Error structures and parameter estimation [PDF]

open access: yes, 2006
This article proposes a link between statistics and the theory of Dirichlet forms used to compute errors. The error calculus based on Dirichlet forms is an extension of classical Gauss' approach to error propagation.

Parameter Estimation for Sea Clutter Pareto Distribution Model Based on Variable Interval

open access: yesRemote Sensing, 2022
The generalized Pareto (GP) distribution model is often used to describe the amplitude statistical feature of sea clutter. Generally, the parameters of GP distribution are estimated by moments estimators.

Bayesian estimation applied to multiple species [PDF]

open access: yes, 2006
Observed data are often contaminated by undiscovered interlopers, leading to biased parameter estimation. Here we present BEAMS (Bayesian estimation applied to multiple species) which significantly improves on the standard maximum likelihood approach in ...

Multidimensional Single-Tone Frequency Estimation Based on QR Decomposition

open access: yesIEEE Access, 2019
In this paper, the problem of multidimensional single-tone frequency estimation of sinusoids embedded in white Gaussian noise is investigated. By extracting the two-dimensional (2-D) slice matrices from the multidimensional data, we construct a ...
