State-space approaches to ultra-wideband Doppler processing

Holl, David J. January 2007 (has links)
Dissertation (Ph.D.) -- Worcester Polytechnic Institute. Abstract: National security needs dictate the development of new radar systems capable of identifying and tracking exoatmospheric threats to aid our defense. These new radar systems feature reduced noise floors, electronic beam steering, and ultra-wide bandwidths, all of which facilitate threat discrimination. However, in order to identify missile attributes such as RF reflectivity, distance, and velocity, many existing processing algorithms rely upon narrow bandwidth assumptions that break down with increased signal bandwidth. We present a fresh investigation into these algorithms for removing bandwidth limitations and propose novel state-space and direct-data factoring formulations such as: the multidimensional extension to the Eigensystem Realization Algorithm; employing state-space models in place of interpolation to obtain a form which admits a separation and isolation of solution components; and side-stepping the joint diagonalization of state transition matrices, which commonly plagues methods like multidimensional ESPRIT. We then benchmark our approaches and relate the outcomes to the Cramer-Rao bound for the case of one and two adjacent reflectors to validate their conceptual design and identify those techniques that compare favorably to or improve upon existing practices. / Keywords: State-space; Super resolution; Doppler; Direction of arrival; DoA; Singular value; SVDl; DSS. .

THE DESIGN AND CONSTRUCTION OF A C-BAND RAIL-SAR AND AN S-BAND DOPPLER RADAR

Crockett, Donald E., Arnold, David V., Jensen, Michael A. 10 1900 (has links)
International Telemetering Conference Proceedings / October 26-29, 1998 / Town & Country Resort Hotel and Convention Center, San Diego, California / To help students learn the principles of microwave engineering and electromagnetic theory, labs were developed in which the students built a rail-synthetic aperture radar(SAR) and a Doppler radar. These labs gave the students practical experience in the paper design, simulation, construction, testing, and debugging of RF circuits. This paper includes a description of the design, physical construction, the basic operation, and the results from these projects.

Detection and velocity of a fast moving object

Gudipudi, Venkata Naga Manikanta Aditya January 2017 (has links)
Over a past few years, technology is constructing the way humans live. With the rapid growth towards Internet of Things (IOT) and other connected services, companies are investigating the ways to enhance current living conditions. There are several devices that are launched in the market to help people to increase flexibility and most of all, to see beyond what is possible. It is helping us reinforce ourselves in our day to day activities. Even in sports, thanks to the latest technological developments, most people’s lives have been enhanced and simplified. Advances in technology has a huge impact on sports which includes- analysis of sport performance, improvements in design of sports equipment and facilitate coaches to provide feedback on players’ performance. Sports equipment continually undergoing research and development to improve sporting performance ensuring a superior game and positive results. Significant technology such as smart gear is popular among athletes to analyse their performance. The equipment usually includes sensors controlled by microcontrollers. The main contribution of this thesis is to investigate the possibilities of a suitable sports equipment to detect and calculate speed of a fast-moving object and providing the drawbacks while using different sensors. In this thesis, IR/Laser sensors, along with a Doppler radar module were tested to put forward a best suitable method to calculate the speed of a fast-moving object and transmit the data over a network.
