| Abstract: | The various technologies presented herein relate to reducing and/or
filtering undesired artifacts in a SAR image, wherein the artifacts are
generated by RF interference resulting from a communication signal being
included in a radar return which also comprises radar clutter. The radar
return is separated into two subapertures, a first subaperture comprising
radar clutter only, and a second subaperture comprising radar clutter and
the communication signal. The communication signal is extracted from the
second subaperture and reapplied to the initially received radar return.
Reapplication of the communication signal to the radar return enables any
undesired artifacts arising from the communication signal to have their
return strength reduced or minimized, while maintaining any desired radar
returns in the SAR image. |
