unpatentable over Flannery in view of
Raudonat and Merlo.
The examiner cites Flannery as teaching a Doppler
radar system that transmits an unmodulated continuous wave
signal and provides dual channel phase related Doppler
signals. Flannery does not suggest that Fourier transform
means are used in the processing of the signals, and the
examiner cites Raudonat to teach the obviousness of processing
Doppler radar signals using the Fourier transform. Merlo
teaches the desirability of using a vehicle’s own velocity to
control a filter which determines the range of Doppler
frequencies which will be considered. The examiner observes
that it would have been obvious to the artisan to replace the
Flannery low pass filters with programmable filters as taught
by Merlo and to use Fourier transform processing as taught by
Raudonat [Final Rejection, pages 2-3].
In our view, the examiner’s analysis is sufficiently
reasonable that we find that the examiner has satisfied the
burden of presenting a prima facie case of obviousness. That
is, the examiner’s analysis, if left unrebutted, would be
sufficient to support a rejection under 35 U.S.C. § 103. The
