Available in PDF, EPUB and Kindle. Book excerpt: An Adaptive Extended Kalman Filter technique was developed to improve the tracking capabilities of an airborne tracking system. A maneuver determination technique was developed as well as an adaptive technique for the probability model of target acceleration. The computer simulation was run using four different types of data. Computation of the acceleration state was inaccurate due to imprecise modeling of the acceleration states. The adaptive technique reduced the range error of the non-adaptive filter. A maneuver was determined when a bias was detected on the range measurement residual. (Author).

Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by TPRC at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemina tion phases of the activity was transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we have concluded that it will be in the interest of all concerned if the printing and distribution of the volume were handled by a well-known publishing house to assure improved service and better communication. Hence, effective with this Volume 18, Masters Theses in the Pure and Applied Sciences will be disseminated on a worldwide basis by Plenum Publishing Corporation of New York. All back issues can also be ordered from Plenum. As we embark on this new partnership with Plenum, we also initiate a new venture in that this important annual reference work now covers Canadian universities as well as those in the United States. We are sure that this broader base will greatly enhance the value of these volumes.

This book was released on 1975 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many aerospace problems include the requirement for precision pointing and tracking from one accelerating vehicle to another. This paper considers the use of Kalman filtering for a general class of high precision pointing and tracking applications and the application of the general framework to a specific problem. A general framework which contains all known error sources is developed for a particular Kalman filter. With a covariance sensitivity analysis, this framework can be used to determine the performance of a reduced order filter and conduct a hardware requirements analysis and trade off. In particular, the paper addresses the application of the general framework for an aircraft to satellite precision tracking problem.

Download or read book Beyond the Kalman Filter Particle Filters for Tracking Applications written by Branko Ristic and published by Artech House. This book was released on 2003-12-01 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: For most tracking applications the Kalman filter is reliable and efficient, but it is limited to a relatively restricted class of linear Gaussian problems. To solve problems beyond this restricted class, particle filters are proving to be dependable methods for stochastic dynamic estimation. Packed with 867 equations, this cutting-edge book introduces the latest advances in particle filter theory, discusses their relevance to defense surveillance systems, and examines defense-related applications of particle filters to nonlinear and non-Gaussian problems. With this hands-on guide, you can develop more accurate and reliable nonlinear filter designs and more precisely predict the performance of these designs. You can also apply particle filters to tracking a ballistic object, detection and tracking of stealthy targets, tracking through the blind Doppler zone, bi-static radar tracking, passive ranging (bearings-only tracking) of maneuvering targets, range-only tracking, terrain-aided tracking of ground vehicles, and group and extended object tracking.

Download or read book The Extended Preferred Ordering Theorem for Radar Tracking Using the Extended Kalman Filter written by Donald Myron Leskiw and published by . This book was released on 2019-08-08 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: A certain problem in nonlinear estimation exists in radar tracking. Usually radar detections provide instantaneous position measurements in radar (polar) coordinates at discrete times, while the tracks (estimated positions and motions over continuous time) are determined in rectangular coordinates using the Kalman filter, which is a linear estimator. And so most radar tracks tend to be biased and their covariance matrices inconsistent with the true ones. Of course, some techniques have been proposed for "debiasing" them. It is shown here, however, that the leading one can make the biases worse; a remedy for that is provided. But the focus here is upon the extended Kalman filter, which is a locally linearized estimator. In an earlier work by this author - dubbed the Preferred Ordering Theorem (POT) - it was shown that the linearization errors in the range direction can be virtually eliminated by using the measurement components of a detection recursively in the order azimuth first, range last. But that has a fundamental limitation, namely, that "preferred" order, and a range measurement component is required. So here a new version is provided, dubbed the Extended-POT (EPOT). Under it, not only is the update more efficient than the POT's, the measurements may be used in any order with virtually the same results.

Download or read book Development of an Adaptive Kalman Target Tracking Filter and Predictor for Fire Control Applications written by and published by . This book was released on 1977 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the development of an adaptive Kalman filter for target tracking and prediction that was subsequently implemented in the digital MARK 68 Gunfire Control System (GFCS) as part of the Gunnery Improvement Program. The discrete Kalman filter is introduced along with a brief discussion of its selection for this application. The general problem of target modeling was presented with emphasis on conventional polynomial models and their convergence properties. A stochastic target model, a first order Markov process in acceleration, was introduced, and the advantages over the polynomial were models explored. A dual bandwidth adaptation algorithm with associated maneuver detection logic was developed and favorably compared with more conventional adaptation methods. A Kalman filter to handle serially correlated observation error (without state vector augmentation) was found, restructured to improve the computational efficiency and exercised to determine parametric sensitivity to correlation effects. Prefiltering, or data compression techniques, were studied and found to significantly reduce required computation with negligible degradation in performance. Square root covariance propagation (in single precision) was found to be considerably more efficient (by a factor of 4.5) than double precision covariance for the particular filter model and computer for this application. The three-dimensional filtering problem was approached by first developing the optimal nonlinear filter as a standard and then evaluating on a relative basis several suboptimal linearized versions.

Available in PDF, EPUB and Kindle. Book excerpt: Provides a state-of-the-art presentation of optimal radar tracking systems based on the sophisticated Altair radar, which uses Kalman filtering to perform optimal long-range tracking of ballistic missile warheads. This engineering example offers a means for explaining Kalman filter theory and many other technical issues critical to the design of a modern optimal radar tracking system, all in arelatively simple manner. Material includes discussion of feedback control, modulation and demodulation of signals, digital sampled-data systems, digital computer simulation, statistical analysis of random signals, detection and tracking processes in a radar system. This study of Altair features a considerable amount of detail concerning the operation of a complex electronic system, thereby presenting a study that is unusual in the unclassified literature.
