This research is on Computer Simulation of Radar Cross Section (RCS) of spherical object. Radar Cross Section (RCS) is one of the key parameters in the detection of targets. It is used to describe the amount of scattered power from a target towards the radar. It has been observed that the radar designers use RCS of spherical shaped objects as a reference point in determining the RCS of other objects. This is because the RCS of a sphere tends to be constant. In this research, RCS of a sphere were simulated in the three regions of the sphere using matlab simulation tool to determine the exact region of the sphere where the RCS is constant. Observations during simulation of the data in the Rayleigh region showed that in this region, RCS dB (m2) varied approximately in amplitude and phase. For the MIE or resonance region, it was seen that there were a significant phase variation of the graph, which meant that the target was significant and all parts contributed to the scattering in this region. Furthermore, it was observed that the backscattered RCS for a perfectly conducting sphere was constant in the optical region.
