Non-linear Kalman filters comparison for generalised autoregressive conditional heteroscedastic clutter parameter estimation
(Institution of Engineering and Technology, 2019-08-01)
In this work, the authors analyse the estimation of the generalised autoregressive conditional heteroscedastic (GARCH) process conditional variance based on three non-linear filtering approaches: extended Kalman filter ...

Adaptive Radar Detection Algorithm Based on an Autoregressive GARCH-2D Clutter Model
(Institute of Electrical and Electronics Engineers, 2014-06)
We propose a model for radar clutter that combinesan autoregressive (AR) process with a two-dimensional generalizedautoregressive conditional heteroscedastic (GARCH-2D) process.Based on this model, we derive an adaptive ...
Spectral parameter estimation of CAT radar echoes in the presence of fading clutter
(American Geophysical Union, 1982-07)
The 430 MHz, 2 MW radar at the Arecibo Observatory is currently being used as a stratospheric-troposheric (ST) radar. One of the problems in the automatic analysis of the signals come from the very large amplitude of the ...
