Abstract

Ground penetrating radars (GPR) are widely used for detection of underground buried objects. Synthetic aperture radars (SAR) are common instruments for land remote sensing. GPRs with synthetic aperture radar technique (GPR-SAR) are popular instruments to obtain image of the buried objects. To know about dielectric contents, position and shape of the buried target objects, ordinary GPR-SAR is insufficient, because angle between transmit and receive antenna is fixed. Therefore, information is lacked, mainly about microwave propagation velocity of soil which affects measurement accuracy of position of various buried objects. Multi-angle GPR-SAR, a new method, is proposed and can change angle between transmit and receive antennas. In the multi-angle GPR-SAR, a lot of angle points between the antennas can be set, and much more detailed information can be obtained related to buried objects and surrounding soil. A new indoor experiment instrument of full-polarimetric, multi-angle and bi-static GPR-SAR have been developed, which enables us to evaluate possibility of imaging various already-known buried objects. Outline of the instrument is introduced, and polarimetric calibration and imaging capability are verified.
