This book was released on 2000 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of a model to assess the radar performance capabilities of a sparse aperture space-based OMTI radar system is presented. Airborne radars have provided reliable detection of moving targets for many years. Recent technological advancements have allowed the deployment of radar systems in space to improve global coverage. Additional radar performance benefits from space-based platforms are made possible with clusters of collaborative microsatellites. Using quantitative capability metrics, specifically the probability of detection and the minimum detectable velocity, the performance of the radar system can be modeled to enable effective and unbiased comparison of candidate system architectures. A design study based on the space-based GMTI radar reference mission for the Air Force's TechSat 21 program was conducted to identify viable system design configurations that satisfy specific radar performance requirements. A comprehensive analysis of the cost, reliability, and performance considerations for the complete TechSat 21 system is proposed.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the product of five and a half years of research dedicated to the und- standing of radar interferometry, a relatively new space-geodetic technique for m- suring the earth’s topography and its deformation. The main reason for undertaking this work, early 1995, was the fact that this technique proved to be extremely useful for wide-scale, fine-resolution deformation measurements. Especially the interf- ometric products from the ERS-1 satellite provided beautiful first results—several interferometric images appeared as highlights on the cover of journals such as Nature and Science. Accuracies of a few millimeters in the radar line of sight were claimed in semi-continuous image data acquired globally, irrespective of cloud cover or solar illumination. Unfortunately, because of the relative lack of supportive observations at these resolutions and accuracies, validation of the precision and reliability of the results remained an issue of concern. From a geodetic point of view, several survey techniques are commonly available to measure a specific geophysical phenomenon. To make an optimal choice between these techniques it is important to have a uniform and quantitative approach for describing the errors and how these errors propagate to the estimated parameters. In this context, the research described in this book was initiated. It describes issues involved with different types of errors, induced by the sensor, the data processing, satellite positioning accuracy, atmospheric propagation, and scattering character- tics. Nevertheless, as the first item in the subtitle “Data Interpretation and Error Analysis” suggests, data interpretation is not always straightforward.

This book was released on 2004 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space-Based Radar (SBR) processing is a processor- and communication-intensive HPEC application that presents unique design challenges. This talk will concentrate on the presentation of simulation results of mapping a parallel Ground Moving Target Indicator (GMTI) application on an embedded multiprocessor satellite processing system featuring a RapidIO interconnection network. We consider three partitionings of a real-time GMTI algorithm executed on systems of different sizes and topologies. Each partitioning's system performance and algorithm scalability on various RapidIO systems is examined.

Book Synopsis Computer Simulations of Canada's RADARSAT2 GMTI. by : Shen Chiu
Download or read book Computer Simulations of Canada's RADARSAT2 GMTI. written by Shen Chiu and published by . This book was released on 2000 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Canada's RADARSAT2 commercial SAR satellite will have an experimental operating mode that will allow ground moving target indication (GMTI) measurements to be made with received data. This mode is also called MODEX (Moving Object Detection Experiment). In the GMTI or MODEX mode of operation the spacecraft's radar antenna is partitioned into two apertures that sequentially observe the scene of interest from the same points in space. Data is simultaneously and coherently received from both apertures and is down-linked in parallel channels for processing to extract moving target radial speeds in their SAR image context. This paper provides an analysis of SAR-GMTI performance based on computer modeling and simulations. Two SAR-MTI processing approaches are being explored. One utilizes the classical DPCA clutter cancellation technique to provide sub-clutter visibility for dim slowly moving targets. The other is based on the along-track (temporal) SAR interferometer technique, where amplitude and phase information of the slow-moving tar gets are exploited to extract them from the dominant clutter background. Performances of the two approaches are compared.

Book Synopsis Comparisons of the Detection Performance of a Space-Based Radar System Using Different Antenna Systems and Aperture Illuminations by : B. J. Rook
Download or read book Comparisons of the Detection Performance of a Space-Based Radar System Using Different Antenna Systems and Aperture Illuminations written by B. J. Rook and published by . This book was released on 1986 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comparisons have been made of the results of the detection performance of a space-based radar (SBR) system using uniformly-illuminated circular apertures, and the same apertures with Taylor weighting applied. From the studies, it is shown that the detection performance of an SBR system can be greatly improved with the application of the latter form of weighting. For the comparative studies, two antenna systems with the same physical dimensions were used, (1) a Taylor-weighted circular aperture for transmitting and receiving, and (2) a uniformly-illuminated circular aperture for transmitting, and the same aperture but with Taylor weighting applied for receiving. These comparative studies show that when antenna system (1) was used, 45.0 dB Taylor weighting was required in order to achieve the optimum SBR detection performance whereas for antenna system (2), 55.0 dB was required to give the same detection performance.

This book was released on 2006-01-02 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chapters in this volume were presented at the July 2005NATO Advanced Study Institute on Advances in Sensing with Security App- cations. The conference was held at the beautiful Il Ciocco resort near Lucca, in the glorious Tuscany region of northern Italy. Once again we gathered at this idyllic spot to explore and extend the reciprocity between mathematics and engineering. The dynamic interaction - tween world-renowned scientists from the usually disparate communities of pure mathematicians and applied scientists which occurred at our six previous ASI’s continued at this meeting. The fusion of basic ideas in mathematics, biology, and chemistry with ongoing improvements in hardware and computation o?ers the promise of much more sophisticated and accurate sensing capabilities than c- rently exist. Coupled with the dramatic rise in the need for surveillance in innumerable aspects of our daily lives, brought about by hostile acts deemed unimaginable only a few short years ago, the time was right for scientists in the diverse areas of sensing and security to join together in a concerted e?ort to combat the new brands of terrorism. This ASI was one important initial step. To encompass the diverse nature of the s- ject and the varied backgrounds of the anticipated participants, the ASI was divided into three broadly de?ned but interrelated areas: the - creasing need for fast and accurate sensing, the scienti?c underpinnings of the ongoing revolution in sensing, and speci?c sensing algorithms and techniques.
