Abstract
In our previous works, we presented a fundamentally new method for detecting underground rectilinear objects by means of georadars. To improve the lateral resolution of the proposed method, a variant of this method using two transmitting antennas fed in antiphase was proposed. In this letter, we extend the previous work and present a deeper analysis of this method. It is shown that using the proposed method, a significant increase in both the relative area reflectivity (RAR) of rectilinear objects and the lateral resolution in the detection of underground narrow objects can be achieved. Our calculations show that using this method, it is possible to achieve a high horizontal resolution of the order of 0.2 m at depths of 20–30 m. The dependencies of RAR on the object’s depth and width are calculated and presented. This method is applicable for both orthogonal and any other scanning scheme.
