Appeal No. 2006-2067
Application 10/437,836
analyzing the returns to determine the elevation according to one or more of
the following modalities:
phase monopulse(PM)
amplitude monopulse(AM), and
time delay response(TDR).
13. A multi-mode altimeter system for use on a platform that moves relative to
a terrain of interest, the system comprising:
a multi-channel antenna operative to generate overlapping antenna patterns
on a terrain partitioned into a plurality of sampling lanes; and
a processor to perform elevation measurements of the terrain, including time-
delay-response(TDR), amplitude-monopulse(AM) and phase-monopulse(PM)
operational modes.

THE REJECTIONS
Claims 1-20 stand rejected under 35 U.S.C. § 103 as being unpatentable over
Madsen in view of Marino.
OPINION
The rejection is reversed as to claims 1-12 and 17-20, and affirmed as to claims 13-
16.
Claims 1-12 and 17-20
We need to address only the independent claims, i.e., claims 1, 6, 7 and 17. Claims
1 and 7 require a method for remotely sensing terrain elevation comprising sampling returns
