RCS ($\sigma$) is defined as $4\pi$ times the ratio of the power reflected back toward the source to the power intercepted by the target. Mathematically: $$ \sigma = \lim_R \to \infty 4\pi R^2 \frac^2E_i $$ Where $E_s$ is the scattered field strength and $E_i$ is the incident field strength. Measured in $m^2$ (or dBsm), a stealth aircraft like the F-35 has an RCS comparable to a metal marble ($\sim 0.001 m^2$), while a conventional fighter is as large as a barn door ($\sim 5 m^2$).

There are several techniques for reducing the RCS and LCS of a target:

Use NURBS (Non-Uniform Rational B-Splines) to design faceting or conformal shaping. Tool: The PDF often includes MATLAB scripts for RCS vs. aspect angle. radar and laser cross section engineering pdf

Build a scaled model (1:10 for radar, 1:1 for laser) and test in an anechoic chamber.

No modern is complete without discussing simulation. Physical testing (range testing) is expensive. Instead, engineers rely on computational electromagnetics (CEM).

Before delving into the engineering complexities, it is vital to define the metrics. A "Cross Section" in this context is a measure of how detectable an object is by a specific sensor system. It is not a physical area, but rather an "effective area" that scatters energy back to the source.
