Automatic sensor fusion is required to improve the performance of ground penetrating radar (GPR)-metal detector multi-sensor systems. The existing version of the Kalman filter-based detection algorithm has been adapted for automatic detection and discrimination of landmines in metal detector data. In this algorithm, multi-channel metal detector output data are fused to produce a distribution of probabilities of the presence or absence of a target. Performance of this algorithm has been assessed using data obtained by burying a number of simulant landmines, canonical targets and shrapnel in different soil types.","PeriodicalId":135740,"journal":{"name":"IGARSS 2001.

The experiment site is the Pyla dune, a bare sandy area allowing high signal penetration and presenting large subsurface wet structures (paleosoils) at varying depths. The SAR penetration depth is estimated by inverting a scattering model for which the sub-surface structure geometric and dielectric properties are determined by the GPR data analysis. We observed a specific phase difference between HH and VV channels, due to a wet layer covered by dry sand. Our results suggest that airborne radar systems in a lower frequency range (P-band) should be able to detect sub-surface moisture down to at least ten meters.","PeriodicalId":135740,"journal":{"name":"IGARSS 2001.

As in any linear method, errors in the data and transformations are propagated in the solution. This paper presents an analytical derivation showing how error in the data affects the solution of the LMM. We show that for simple types of input error, the solution error can be expressed as a function of the end members. We present examples of 2 and 3 end member problems for both the constrained and the unconstrained solution. We show that the error in the fractions is inversely related to the spectral angle between end members in the unconstrained solution, and inversely related to the Euclidean distance between end members in the constrained solution.","PeriodicalId":135740,"journal":{"name":"IGARSS 2001.

We present two independent methods for this estimation.

In the first experiment high resolution polarimetric range profiles of the wake produced by a displacement hull vessel were recorded at X and Ku band frequencies. Periodic transient enhancements were observed, generated by wave breaking events precipitated by the superposition of the dominant wake components with the crests of the incoming swell. In order to identify the induced wave breaking events unambiguously, the measurements were carried out for ship headings directly into and directly opposed to the prevailing waves. Clear confirmation of the proposed mechanism was thus demonstrated. The second experiment employed a planing hull vessel. Because of the high speed of this ship, the measurement geometry was changed to set one of the diverging wake arms perpendicular to the radar beam. High resolution polarimetric range profiles were then recorded at X and Ku band frequencies.","PeriodicalId":135740,"journal":{"name":"IGARSS 2001. Scanning the Present and Resolving the Future.

The wire-aligned dihedral we proposed has a thin dielectric frame to hold the wires, requiring no base material. In October 2000 we made a polarimetric calibration experiment of the X-band synthetic aperture radar, a part of the Pi-SAR. Those polarization selective dihedrals, together with conventional trihedrals, were deployed in the experiment. Preliminary results of the image data analysis showed that they were of practical use for polarimetric calibration, while there were some errors in reflected power probably due to their structure and their misalignment. It also showed that the corner reflectors were useful to determine phase calibration coefficients that is phase imbalances between polarimetric channels in the radar hardware.","PeriodicalId":135740,"journal":{"name":"IGARSS 2001.

Throughout the years, the application of remote sensing and geographic information system technology has undergone numerous modifications and revisions to enhance their ability to control, reduce, and estimate the origin of non-point source pollution. Yet, there is still a considerable amount of uncertainty surrounding the use of this technology as well as its modifications. This research demonstrates how the application of remote sensing, geographic information system, and global positioning system technologies can be used to assess water quality in the Wheeler Lake watershed. In an effort to construct a GIS based water quality database of the study area for future use, a land use cover of the study area will be derived from LANDSAT Thermatic Mapper (TM) imagery using ERDAS IMAGINE image processing software. A Digital Elevation Model of the Wheeler Lake watershed was also from an Environmental Protection Agency Basins database. Physical and chemical properties of water samples including pH, Total Suspended Solids (TSS), Total Fecal Coliform (TC), Total Nitrogen (TN), Total Phosphorus (TP), Biological Oxygen Demand (BOD), Dissolved Oxygen (DO), and selected metal concentrations were measured.","PeriodicalId":135740,"journal":{"name":"IGARSS 2001.
