and devices useful in separating the strongest of a plurality of
linearly combined signals and suppressing the strongest frequency
for the purpose of defeating electronic jamming. See Baghdady,
column 1, lines 9 through 17. Baghdady further teaches that the
methods and techniques may be employed in the on-line measurement
of relative powers of a desired signal and undesired signal or
noise powers. See column 1, lines 17 through 20. However, we do
not agree with the Examiner that Baghdady is at all concern with
the problem of determining the direction of arrival of a
traveling spectrally spread signal of wavefront of measurable
center-frequency wavelength.
We find that there would have been no motivation, suggestion
or reason for those skilled in the art to have used the features
of the anti-jamming circuitry of Baghdady in the direction
finding equipment disclosed in Green to obtain a method or
apparatus for determining the direction of arrival of a traveling
spectrally spread signal wavefront of measurable center-frequency
wavelength. At best, those skill in the art would only be
directed to using the Baghdady’s approach to distinguish
extraneous noise from a single spectrum line signal which carry
information data that identify the direction arrival of the
instant wavelength. Thereforth we will not sustain the
