Empirical Method of RCS Estimation
•Skolnik (1980) suggested a formula to estimate the median RCS of a ship based on its displacement and the frequency of operation of a given seeker:
•
•
•For our design, with a displacement of around 7000 LT and a frequency of operation of 0.3 GHz:
•
•
•This approximation varies with the angle. 13 dB (for broadside) are added and 8 dB (for minima) are subtracted.
In summary, the empirical method estimates RCS as a function of a ship’s displacement and the operating frequency of an enemy seeker.

Using our ship’s displacement of 7000 long tons and a seeker frequency of 0.3 gigahertz,
we estimated the RCS to be between 34 and 55 decibel square meters depending upon the target angle.
