Abstract:

The Conformal C-Band/Multi-band Antenna project will support the AWS-3 auction by providing the technology to integrate C-Band or multi-band telemetry(TM) antennas on test articles such as missiles, weapons, or aircraft. These test articles would then provide C-Band or multi-band TM data to ground station receivers that are relocated to the C-Band frequency range through the AWS-3 Spectrum Relocation Fund program. This project would advance the technology of antennas in the C-Band region for test article TM integration. Successful use of C-Band and Multi-Band antennas for aeronautical m

This thesis evaluates the potential for using line of sight returns and return signals from underneath a forest canopy using X-band, airborne synthetic aperture radar (SAR) tomography. Approximately 30% of the Earth’s land surface is covered by vegetation, therefore global digital elevation models (DEMs) contain a signal from the forest canopy and not the ground. By uncovering new techniques to find the ground signals, using data collected from airborne platforms as verification, such procedures could be applied to currently operational and future X-band, spaceborne systems with the aim of res

Certain applications require topographic surveys below the vegetation cover. The use of radars with long wavelengths, such as L- and P-band, allows signal penetration through the forest volumetric structure. However, the interferometric phase center, resulting from this interaction, may be closer to or farther from the ground depending on the baseline and polarizations used. Recently, improvements in polarimetric synthetic aperture radar interferometry with the random volume over ground model have allowed the generation of terrain models with considerably increased accuracy.

Abstract:

Synthetic aperture radar polarimetry is one of the current developments in the field of remote sensing, due to the ability of delivering more information on the physical properties of the surface. It is known as the science of acquiring, processing and analysing the polarisation state in an electromagnetic field. The increase of information with respect to scalar radar comes at a price, not only for the high cost of building the radar system and processing the data or increasing the complexity of the design, but also for the amount of effort needed to calibrate the data.

In this thesis we develop algorithms for the processing of textures and images using a ladder-based biorthogonal directional filter bank (DFB). This work is based on the DFB originally proposed by Bamberger and Smith. First we present a novel implementation of this filter bank using ladder structures. This new DFB provides non-trivial FIR perfect reconstruction systems which are computationally very efficient. Furthermore we address the lack of shift-invariance in the DFB by presenting a novel undecimated DFB that preserves the computational simplicity of its maximally decimated counterpart.

In order to enhance the applications of SAR data, the geometric correction is a must. Thus, the generated ortho-image can be registered with other GIS data layers. The traditional methods for the rectification of SAR imagery adjust orbit polynomials according to ground control points. From direct georeferencing point of view, this paper investigates the feasibility of Radar back projection and analyzes the accuracy

Abstract:

SAR Wave INteraction for Natural Targets Over Land (SWINTOL) is a project funded by the European Space Agency. The study’s goal is to better understand the interaction of high frequency radar (> X-band) with vegetation and soils, in order to drive the development of a high-frequency electromagnetic model to simulate SAR imagery at high resolution (< 1 m). Existing models work well at C and X band frequencies, but do not work properly at higher frequencies. Cranfield University’s role in this project was to provide the field data necessary for model validation and development. Radar imagery was

Abstract:

Even though major advances in economic theory and modelling have in some cases furthered our understanding of how the economy works, the system as a whole has become more complex. If policymakers had perfect knowledge about the actual state of the economy, the various transmission mechanisms as well as the true underlying model, monetary intervention would be greatly simplified. In reality, however, the monetary authorities have to contend with considerable uncertainty in relation to the above-mentioned factors. This said, uncertainty has mostly been neglected in both the theoretical an

碩士<br>國立成功大學<br>測量工程學系碩博士班<br>92<br>Because fully polarimetric SAR (POLSAR) provides more information about the scattering characteristics of the earth’s surface, it enables a more accurate classification than single-channel and single-polarization SAR do. POLSAR gives all polarimetric properties in the covariance matrix. Due to speckle noise of POLSAR data, the fine pattern is difficult to be identified and the true value of back-scattering is contaminated by noise. Hence, the speckle noise filter approach is utilized to reduce noise disturbance. Moreover, the fuzzy approach is utilized to ta

The Taiwan High Speed Railway (THSR) passes through a serious subsidence area in Sijhou Township, where subsidence poses a serious threat to its operation. A major issue is to effectively monitor land subsidence. Multi-temporal InSAR (MT-InSAR) techniques, involving the processing of multiple acquisitions in time, can measure ground displacements to an accuracy comparable to that of precision leveling. This study uses three MT-InSAR methods, including PSInSAR, StaMPS/MTI and TCPIn

While images are continuously being acquired and archived, existing methodologies have proved inadequate for analyzing such large volumes of data. As a result, a vital demand exists for new concepts and methods to deal with high-dimensional datasets. In this paper,we fuse hyperspectral imaging and synthetic aperture radar imaging.

Abstract:

Agricultural production is becoming increasingly important as the world demand increases. On the other hand, there are several factors threatening that production such as the climate change. Therefore, monitoring and management of different parameters affecting the production are important. The current study is dedicated to two key parameters, namely agricultural land cover and soil-moisture mapping using X- and L-Band Synthetic Aperture Radar (SAR) data. Land-cover mapping plays an essential role in various applications like irrigation management, yield estimation and subsidy control. A model
