Fully Polarimetric Ground Penetrating Radar WISDOM
نویسنده
چکیده
The Ground Penetrating Radar (GPR) WISDOM is designed to be part of 2018 ExoMars Rover payload. The main scientific objective of WISDOM is to characterize the material distribution within the first few meters of the Martian subsurface and to search for evidence of past and present life on Mars. The WISDOM radar will provide a penetration depth of about 3 meters with a resolution of a few centimetres within the Martian soil. A preliminary “real time” subsurface analysis supports the drill operations in finding places of high scientific interest and low risk. The joint data interpretation together with the drill team will significantly support the radar calibration. This presentation will focus on instrument performance depending on the accommodation of the WIDOM antennas aboard a Mars rover. Preliminary tests in the lab and in the field have shown that apart from the electronic unit the fully polarimetric antenna arrangement is one key element for the localization and characterization of buried scatterers and for the construction of a three dimensional subsurface map of the shallow Martian ground.

Polarimetric radar signature of masonry walls
A ground-penetrating radar with polarimetric capability has been used for investigating masonry walls. The obtained results show that hollow spaces inside masonry give a well-detectable polarimetric signature that can be usefully used for detecting internal cavities in walls, and for characterizing the masonry. r 2007 Published by Elsevier Ltd.
متن کاملTarget Detection Studies Using Fully Polarimetric Data Collected by the Lincoln Laboratory MMW SAR
Under DARPA sponsorship, MIT Lincoln Laboratory is investigating the detection and identification of stationary ground targets in high resolution, fully polarimetric, synthetic aperture radar (SAR) imagery. This paper compares two techniques for improving target detection performance by optimally processing the fully polarimetric SAR data.
متن کاملOptimal Processing of Polarimetric Synthetic-Aperture Radar Imagery
The Advanced Detection Technology Sensor can detect, discriminate, and classify stationary ground targets—during the day or night—even through cloud cover, fog, smoke, dust, or rain. The sensor is a coherent, fully polarimetric, 35-GHz syntheticaperture radar (SAR) with a resolution of 1 ft × 1 ft. And, to minimize SAR speckle while preserving image resolution, it uses the polarimetric whitenin...
متن کاملPolarimetric Characteristics of Fully Polarization Sar Image Observed by Ground-based Sar System
Ground-Based SAR system that obtains a high resolution 2D image on the ground is a new type of SAR system such as air-borne and space-borne SAR. The measured fully polarimetric SAR images with HH, HV, VH, and VV were focused using the Deramp-FFT (DF) algorithm in terms of their image formation principles. SAR polarimetry technique is concerned with control of the polarimetric properties of rada...
