| Abstract: | The various technologies presented herein relate to the determination of
whether a received signal comprising radar clutter further comprises a
communication signal. The communication signal can comprise of a
preamble, a data symbol, communication data, etc. A first portion of the
radar clutter is analyzed to determine a radar signature of the first
portion of the radar clutter. A second portion of the radar clutter can
be extracted based on the radar signature of the first portion. Following
extraction, any residual signal can be analyzed to retrieve preamble
data, etc. The received signal can be based upon a linear frequency
modulation (e.g., a chirp modulation) whereby the chirp frequency can be
determined and the frequency of transmission of the communication signal
can be based accordingly thereon. The duration and/or bandwidth of the
communication signal can be a portion of the duration and/or the
bandwidth of the radar clutter. |
