Patent ID: 8212710

Claim:
A synthetic aperture radar comprising: a back projection processor coupled to a display and a radar configured on a truck, the back projection processor comprising instructions stored in a memory and executable on a computing system, the back projection processor operable to: receive a plurality of return signals from the radar as the truck is moved with respect to a building, the plurality of return signals generated by the radar by stepping a transmitted radio-frequency signal from 0.5 Giga-Hertz to 2.0 Giga-Hertz, the plurality of return signals representative of electro-magnetic radiation reflected from the building; generate a dynamic image of one or more walls of the building from the plurality of return signals by varying a squint angle of the plurality of return signals, the squint angle varied by modifying a back projection filter, the back projection filter comprising a spatial filter or a doppler filter; and display the dynamic image on the display.
