A method and system for detecting the presence of subsurface objects within a medium is provided. In some embodiments, the imaging and detection system operates in a multistatic mode to collect radar return signals generated by an array of transceiver antenna pairs that is positioned across the surface and that travels down the surface. The imaging and detection system pre-processes the return signal to suppress certain undesirable effects. The imaging and detection system then generates synthetic aperture radar images from real aperture radar images generated from the pre-processed return signal. The imaging and detection system then post-processes the synthetic aperture radar images to improve detection of subsurface objects. The imaging and detection system identifies peaks in the energy levels of the post-processed image frame, which indicates the presence of a subsurface object.
A method performed by a computing device for generating an image frame from multistatic ground-penetrating radar (“GPR”) return signals of multiple transceivers, the return signals being acquired by multiple receivers from each signal emitted by each of multiple transmitters, the method comprising:
A computer-readable storage device storing computer-executable instructions for controlling a computing device to generate an image frame from multistatic ground-penetrating radar (“GPR”) return signals of multiple transceivers, the return signals being acquired by multiple receivers from each signal emitted by each of multiple transmitters, by a method comprising:
