Figure 6.11b. Clutter RCS entering the radar for the aircraft case.
The MATLAB program
Ðmyradar_visit6.mÑ
was developed to calculate and
plot the CNR and SIR for
ÐMyRadarÑ
design case study. It is given in Listing
6.2 in Section 6.6. This program assumes the design parameters derived in
Chapters 1
and
2.
