Radar Cross Secti<strong>on</strong><br />
The <strong>radar</strong> cross secti<strong>on</strong> (σ) of a target is the “equivalent area” of a flat-plate mirror:<br />
♦<br />
♦<br />
That is aligned perpendicular to the propagati<strong>on</strong> directi<strong>on</strong> (i.e., reflects the signal directly<br />
back to the transmitter) and<br />
That results in the same backscattered power as produced by the target<br />
Radar cross secti<strong>on</strong> is extremely difficult to predict and is usually measured using scaled models<br />
of targets<br />
