Different tools for clutter mapping

Abstract

Stationary clutter arises in a wide area of different radar or sonar applications. Without adaption to a non-uniform clutter distribution, tracking algorithms try to initialize tracks in these areas repeatedly while - in most cases - there is no target to be found. The intention of this paper is to discuss different ways to enable clutter mapping in order to use this as an efficient tool for target tracking algorithms. The methods will be applied to the Range/Doppler tracking task in a multistatic passive radar application, and the performances of the different algorithms are discussed.
