van Rossum, W.L. (author), de Wit, J.J.M. (author)Through-wall radar allows for remote intelligence of building interiors including stand-off detection and tracking of persons inside a building. However, reliable radar tracking of people inside a building is not trivial. Conventional, monostatic through-wall radar measures the backscatter of moving people. The backscatter from a human is...article 2017

Theil, A. (author), van Ewijk, L.J. (author), TNO Defensie en Veiligheid (author)Wind turbines located in the vicinity of a radar system may affect the system's detection and tracking capability. A description of adverse effects is given in the paper for both primary and secondary radar. In order to judge the consequence of the shadowed volume cast by a wind turbine, results of radar performance analyses are presented. It is...conference paper 2007

de Theije, P.A.M. (author), Groen, J. (author), TNO Defensie en Veiligheid (author)This paper describes a simulated data set that can be used for tracker evaluation. The data set is generated in the framework of the Multistatic Tracking Working Group (MSTWG). The simulations are carried out using the TNO SIMONA simulator, which can generate raw hydrophone data for an arbitrary number of sources, receivers, and targets. All of...conference paper 2006

Stefano, C. (author), Doug, G. (author), de Theije, P.A.M. (author), TNO Defensie en Veiligheid (author)This paper provides an overview of the special session on multistatic sonar and radar tracking at FUSION 2006. This includes background on the multistatic tracking working group, a brief description of the datasets and trackers that compose this working group at present, and a detailed discussion of a proposed set of tracker performance metrics....conference paper 2006

TNO Defensie en Veiligheid (author), de Visser, M. (author), Schwering, P.B.W. (author), de Groot, J.F. (author), Hendricks, E.A. (author)We present new techniques for passive ranging with a dual-band IR search and track (IRST) sensor aboard a ship. Three distance estimation methods are described: the atmospheric propagation model, the apparent surface of the target, and target motion analysis (TMA). These methods are tested on the sensor output of real data during cold water...article 2006

TNO Fysisch en Elektronisch Laboratorium (author), Kester, L.J.H.M. (author)The purpose of a tracking algorithm is to associate data measured by one or more (moving) sensors to moving objects in the environment. The state of these objects that can be estimated with the tracking process depends on the type of data that is provided by these sensors. It is discussed how the tracking algorithm can adapt itself, depending on...conference paper 2003
