Book Synopsis Power Line Detection for Millimeter-wave Radar Video by : Qirong Ma
Download or read book Power Line Detection for Millimeter-wave Radar Video written by Qirong Ma and published by . This book was released on 2012 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: To ensure the flight safety of helicopters, millimeter-wave radar imaging systems have been developed in both industry and academia. One application of such radar systems is to image the high-voltage power lines, and thus help the pilot to avoid power-line-strike accidents. In this dissertation, we present automatic power line detection algorithms for the radar video. We investigate the defining characteristics of the power lines in the radar video. The power lines appear as parallel straight lines in the radar video, and Hough transform can be employed to detect them. The major challenge is that the radar videos are exceptionally noisy due to the ground return, and the noise points could fall on the same line which results in signal peaks after the Hough transform which are similar to the actual power lines. To differentiate the power lines from the noise lines, in the first part of this dissertation we train a Support Vector Machine to perform the classification. We exploit the Bragg pattern, which is due to the diffraction of electromagnetic wave on the periodic surface of power lines. We propose a set of features to represent the Bragg pattern for the Support Vector Machine classifier. We also propose a slice-processing algorithm which supports parallel processing, and improves the detection of power lines in a cluttered background. As adaptive algorithm is also proposed to integrate the detection results from individual frames into a power line detection decision, in which temporal correlation of the power line pattern across frames is used to make the detection more robust. Simulation results confirm the effectiveness of the proposed algorithm. In the second part of this dissertation, we further propose to utilize particle filter to more formally capture the temporal correlation of the power line objects, while the power-line-specific features are embedded into the conditional likelihood measurement process of the particle filter. Because of the fusion of multiple information sources, the detection of power line is more effective. We also propose a general framework of cascaded particle filters that takes advantage of the independence of different aspects of the object state, and decomposes the original tracking problem in a high-dimensional state space into several simpler cascaded tracking problems in low-dimensional sub-spaces. The reduced-dimensionality simplifies the problem and thus renders the solution more robust. Experimental simulations validate that the proposed approach can significantly improve the power line detection results.

Download or read book Polarimetric Radar Imaging written by Jong-Sen Lee and published by CRC Press. This book was released on 2017-12-19 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent launches of three fully polarimetric synthetic aperture radar (PolSAR) satellites have shown that polarimetric radar imaging can provide abundant data on the Earth’s environment, such as biomass and forest height estimation, snow cover mapping, glacier monitoring, and damage assessment. Written by two of the most recognized leaders in this field, Polarimetric Radar Imaging: From Basics to Applications presents polarimetric radar imaging and processing techniques and shows how to develop remote sensing applications using PolSAR imaging radar. The book provides a substantial and balanced introduction to the basic theory and advanced concepts of polarimetric scattering mechanisms, speckle statistics and speckle filtering, polarimetric information analysis and extraction techniques, and applications typical to radar polarimetric remote sensing. It explains the importance of wave polarization theory and the speckle phenomenon in the information retrieval problem of microwave imaging and inverse scattering. The authors demonstrate how to devise intelligent information extraction algorithms for remote sensing applications. They also describe more advanced polarimetric analysis techniques for polarimetric target decompositions, polarization orientation effects, polarimetric scattering modeling, speckle filtering, terrain and forest classification, manmade target analysis, and PolSAR interferometry. With sample PolSAR data sets and software available for download, this self-contained, hands-on book encourages you to analyze space-borne and airborne PolSAR and polarimetric interferometric SAR (Pol-InSAR) data and then develop applications using this data.

Download or read book Polarimetric Synthetic Aperture Radar written by Irena Hajnsek and published by Springer Nature. This book was released on 2021-03-24 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book focuses on the practical application of electromagnetic polarimetry principles in Earth remote sensing with an educational purpose. In the last decade, the operations from fully polarimetric synthetic aperture radar such as the Japanese ALOS/PalSAR, the Canadian Radarsat-2 and the German TerraSAR-X and their easy data access for scientific use have developed further the research and data applications at L,C and X band. As a consequence, the wider distribution of polarimetric data sets across the remote sensing community boosted activity and development in polarimetric SAR applications, also in view of future missions. Numerous experiments with real data from spaceborne platforms are shown, with the aim of giving an up-to-date and complete treatment of the unique benefits of fully polarimetric synthetic aperture radar data in five different domains: forest, agriculture, cryosphere, urban and oceans.

Book Synopsis Laser Radar by : National Research Council
Download or read book Laser Radar written by National Research Council and published by National Academies Press. This book was released on 2014-03-14 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: In today's world, the range of technologies with the potential to threaten the security of U.S. military forces is extremely broad. These include developments in explosive materials, sensors, control systems, robotics, satellite systems, and computing power, to name just a few. Such technologies have not only enhanced the capabilities of U.S. military forces, but also offer enhanced offensive capabilities to potential adversaries - either directly through the development of more sophisticated weapons, or more indirectly through opportunities for interrupting the function of defensive U.S. military systems. Passive and active electro-optical (EO) sensing technologies are prime examples. Laser Radar considers the potential of active EO technologies to create surprise; i.e., systems that use a source of visible or infrared light to interrogate a target in combination with sensitive detectors and processors to analyze the returned light. The addition of an interrogating light source to the system adds rich new phenomenologies that enable new capabilities to be explored. This report evaluates the fundamental, physical limits to active EO sensor technologies with potential military utility; identifies key technologies that may help overcome the impediments within a 5-10 year timeframe; considers the pros and cons of implementing each existing or emerging technology; and evaluates the potential uses of active EO sensing technologies, including 3D mapping and multi-discriminate laser radar technologies.
