A Tutorial on Bayesian Estimation and Tracking Techniques Applicable to Nonlinear and Non-Gaussian Processes
Abstract
Nonlinear filtering is the process of estimating and tracking the state of a nonlinearstochastic system from non-Gaussian noisy observation data. In this technical memorandum,we present an overview of techniques for nonlinear filtering for a wide varietyof conditions on the nonlinearities and on the noise. We begin with the developmentof a general Bayesian approach to filtering which is applicable to all linear or nonlinearstochastic systems. We show how Bayesian filtering requires integration over probabilitydensity functions that cannot be accomplished in closed form for the general nonlinear,non-Gaussian multivariate system, so approximations are required.
