First Claim
1. A subterranean imaging apparatus comprising:
- an antenna array comprising a plurality of radiating elements, the plurality of radiating elements configured on a land-based vehicle operable to generate electrical signals according to electromagnetic radiation reflected from a subterranean target below a ground surface; and
a synthetic aperture radar (SAR) system coupled to the antenna array and operable to;
transmit the electromagnetic radiation from a first subset of the plurality of radiating elements;
receive the reflected electromagnetic radiation from a second subset of the plurality of radiating elements having a polarity similar to the polarity of the plurality of radiating element of the first subset, the electromagnetic radiation having a frequency that ranges from 0.1 to 2.0 Gigahertz;
generate raw images from the received electrical signals;
generate a weighting according to phase statistics of pixels in the raw images; and
combine the raw images using the weighting to generate a refined image of the subterranean target.

Abstract
In certain embodiments, a subterranean imaging apparatus comprises at least two receive channels configured on a land-based vehicle and a synthetic aperture radar (SAR) system. The at least two receive channels are operable to generate electrical signals according to electromagnetic radiation reflected from a subterranean target below a ground surface. The SAR system is operable to receive the electrical signals from the at least two receive channels, generate raw images from the received electrical signals, generate a weighting according to phase statistics of pixels in the raw images, and combine the raw images using the weighting to generate a refined image of the subterranean target.
