A new RF tomographic technique is proposed in this concept paper for developing RF CAT Scans of buried objects using spectral, spatial/angular, and polarization diversity. This tomographic imaging technique, developed by Wicks and presented in GPR 2004 [1], uses embedded subsurface radiators, delivered by earth-penetrating non-explosive, electronic \"e-bombs\", as the source of strong underground radiated transmissions. Distributed surface-contact sensors are used to collect the tomographic data for relay to a UAV and transmission to a remote site. Three-dimensional imaging algorithms have been developed to detect, image, and characterize deeply buried targets. By embedding the transmitters underground, reduced mutual coupling and EM emissions, and improved signal-to-noise ratios can be achieved. Simple surface SAR experiments over deep mine shafts have been performed to validate the 3D processing algorithms using 2D surface SAR sensor data. WIPL-D models have also been used to simulate the embedded and distributed sensors and to verify the significant enhancement in the received signal-to-noise ratio obtained by burying radiators under the surface.","PeriodicalId":142822,"journal":{"name":"2007 International Waveform Diversity and Design Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129947299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several application considerations have been analyzed in order to successfully acquire and track weak, reflected GPS signals from ground surface. First of all, both RHCP and LHCP antennas are employed so that direct and reflected signals can be acquired simultaneously. The direction of arrival of the signals may be along the reflected signal path or even along the line-of-sight of a particular satellite. Unlike most existing GPS reflection experiment, the goal of the study is to exploit the carrier phase, reflectivity of L1/L2 SNR components of the reflected signals and direct signals for stream fresh water and ocean water object detection. An integer ambiguity resolution algorithm has also been implemented. During the development and test stage, the digital terrain elevation data and high resolution satellite's images has been used and mapped with the integrated software.","PeriodicalId":142822,"journal":{"name":"2007 International Waveform Diversity and Design Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128535200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

No discussion of control would be complete without illuminating the software dimension. An altitude iteration loop into least squares searching for receiver position was modified and enhanced by giving 4 or more pseudo-ranges and ephemeredes and zooming on the plot to detect the search pattern. [1] The software is developed using MATLAB tools, which can display results of the reflected surface area altitude in real time. For the reflected signal application, it has been proven that a GPS receiver cannot smoothly detect reflected signals because under the underground base receiver system cannot smoothly receive the reflected GPS signals when the GPS signals are weak and discontinuously reflected. [2] This problem negatively impacts and reduces application of reflected signals. The design of an integrated receiver system permits smooth reception of the signals reflected by the water or ground. A rapid resolution altimetry method was developed by using surface elevations spectrum with the elevation angle and line of sight theory in the reflecting geometry and atmospheric corrections with ambiguity solution.","PeriodicalId":142822,"journal":{"name":"2007 International Waveform Diversity and Design Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125979479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
