Radar RCS Calculator and Formula

This page describes the Radar RCS calculator and the Radar RCS formula or equation used within it.

RCS stands for Radar Cross Section. This calculator assumes the target is a sphere (i.e., spherical shape).

Example of Radar RCS calculator:

• INPUT: Target radius = 10 meters
• OUTPUT: RCS = 314.159 meter²

Radar RCS Formula or Equation

RCS (Radar Cross Section) varies depending on the shape of the object. Figure 1 illustrates this.
