Clutter Invarient over Time
Figure 2
Large scale radar patterns
are shown in the figure at right. The parameter displayed is received
power (dBm) in PPI scans at an elevation of 2.5°. Data are shown
for four different days, spaced almost evenly throughout the course of
the MAP deployment. Propagation effects tend to produce the change in
general background color between frames. Note that clutter patterns
(the brightest radar echoes) remain invarient over time, an indication
that the radar pointing did not shift during the project. There is
high reliability in using this technique; it is estimated that shifts
as small as 0.25° would be noticed. (More detailed checks have
been performed, but are not presented here).
