The Kalman filter is an optimal recursive least squares estimator, based on the calculations of the conditional mean and the covariance of the probability distribution of the system state. In addition, both the complete tracking system and each filter have been evaluated and their performance has been compared to other filters in the literature. We tackle the problem of localization by zoning, where the objective is to determine the zone where the person resides, instead of its exact position. The second improvement is a method for the online detection of the lack of observability in the scenarios. As resident space object populations grow and satellite propulsion capabilities improve, it will become increasingly challenging for space-reliant nations to maintain space domain awareness using current human-in-the-loop methods.

The integration of inertial data into the motion models is particularly beneficial for this approach. It explains state estimator design using a balanced combination of linear systems, probability, and statistics. In this paper, an optimal-transport-based state estimation algorithm is applied to the debris-tracking problem, with real range data from a single ranging station. In order to detect and track the targets trajectory to perform a proper defense, the targets motion must be simulated so that the tracking is to be done with minimal error. For all the presented models, trajectory simulation was done and the results are summarized in diagrams in this paper. They then provide detailed treatments of all themajor issues in estimation with a focus on applying thesetechniques to real systems. In target tracking, the estimation of an unknown weaving target frequency is crucial for improving the miss distance.

The problem of tracking moving ground targets using seismic sensors is considered in this paper. Whenever white-noise models are not good enough, it is natural to consider a Markov process model. The proposed method uses all the measurements in the network while requiring only local intersensor communication. Rainfall is not only one of the most natural processes on the earth, but also an important factor of flood generation. To honor Professor Bar-Itzhack's memory, as well as his numerous seminal professional achievements, an international symposium was held in Haifa, Israel, on October 14—17, 2012, under the auspices of the Faculty of Aerospace Engineering at the Technion and the Israeli Association for Automatic Control. Finally, we show how populations of reconstructed neutrons can be used to estimate the direction and energy spectrum of nearby simulated neutron sources.

The active aircraft defense problem is investigated for the stochastic scenario wherein a defending missile or a defender is employed to protect a target aircraft from an attacking missile whose pursuit guidance strategy is unknown. Due to the nonlinearities of the sensors characteristics, extended Kalman filter has been used, with different models for stationary and moving targets. Due to the use of state estimation algorithms, the proposed framework has a low per-iteration time complexity, which makes it suitable for solving a large-scale or high-dimensional state estimation problem. The estimation process is commonly carried out in a Kalman framework. This provides the motivation for our current work. Estimation results are presented for different scenarios together with the Cramer-Rao Lower Bound, which quantifies the best achievable estimation accuracy.

With this respect, a crucial assumption for the applicability of this kind of models is that the sampling interval is sufficiently small as compared to the time constants characterizing the variation of the quantities to be estimated. Previous approaches still exhibit low accuracy for pedestrian trajectory prediction, and they are prone to generate infeasible trajectories under complex crowded conditions. The strategy presented herein successfully tracks 203 nonmaneuvering and maneuvering spacecraft using only 24 ground- and space-based sensors. Within the scope of this work, we tackle problems like multimodal densities and sample impoverishment system gets stuck by introducing different countermeasures. Localization of a mobile robot is given to demonstrate the effectiveness of the proposed methods.

The work done has been focused on these last two functions. These three models have been thoroughly studied by Bar-Shalom et al. We also propose mobility models, which we combine with the observation model, in order to correct the estimations by aggregating all available evidence. In this method, a hybrid distance metric is derived from the correlation coefficients of the covariance matrix obtained from the sequential states of individual tracks and the distances between different target states. The performance of proposed technique has been compared to an existing shape estimation method proposed by Wakita.

All experiments were conducted within a 13th century historic building, formerly a convent and today a museum. We also provide convergence results for the proposed algorithms. Regarding the filtering of the measurements, a system that uses two filters in parallel with a selection logic to obtain the estimation of the position of the targets is proposed. To do this, this function has to perform the following tasks: association of measures, correction of biases, and filtering of measures. Particularly, we focus on the case where a set of possible constant target frequencies is known.

The goal of this work is to propose a fast to deploy localization solution, that provides reasonable results in a high variety of situations. The book contains 27 selected, revised, and edited contributed chapters written by eminent international experts. Nevertheless, the Kalman filter algorithm used in proposed method has provisions to tune measurement noise covariance which can be adjusted based on the noise level in speech. The surveillance region includes about 800 targets that exhibit different types of motion. Its performance is evaluated on a real-world dynamic dataset with ground truth for all motions from a motion capture system.

The authorfirst emphasizes detailed derivations from first principles ofeeach estimation method and goes on to use illustrative anddetailed step-by-step instructions for each method that makescoding of the tracking filter simple and easy to understand. Bayesian Estimation and Tracking is an excellent book forcourses on estimation and tracking methods at the graduate level. A wide range of filters has been developed for the purposes of tracking moving objects and approximating their trajectories. The second filter of the tracking system is a robust filter that does not use the map information and is therefore capable of obtaining the estimate in situations where the map-based filter is not landing aircraft, runway excursions, etc. To that end, we propose estimating the weaving frequency using deep neural networks, instead of classical Kalman framework based estimation.
