Patent ID: 7764220

Claim:
A synthetic aperture radar comprising: an image former comprising instructions stored in a memory and executable on a computing system, the image former coupled to a first antenna and a second antenna that are adjacent to and oriented at differing elevational angles relative to one another, the first antenna and the second antenna configured in a land-based vehicle that is operable to move horizontally relative to a building having one or more internal features, the first antenna operable to transmit electro-magnetic radiation toward the building with a frequency in the range of 0.5 to 3.0 Giga-Hertz, the image former operable to: receive a first signal having a first amplitude component from the first antenna and a second signal having a second amplitude component from the second antenna, the first signal and the second signal indicative of electro-magnetic radiation reflected from the building; generate a first image according to the received first signal and a second image according to the received second signal; and generate the third image by generating a height discriminant map comprising pixels corresponding to the first amplitude portions of the first image and the second amplitude pixels of the second image, and filtering the first image using the height discriminant map to form the third image.
