Modern weapons systems often introduce Radar Cross Section (RCS) specification in addition to other more conventional requirements such as speed, weight, and payload. Development of increasingly sophisticated Radar detection systems threatens to reduce the mission effectiveness of many type of this modern platforms (such as Fast ships Strong attention is now being given to methods of increasing the Survivability by reducing detectability with Radar Cross-Section Reduction (RCSR). Usually fast ships operate in the near shores, so that with considering the probability of tracking these ships in short operational range from shore, the RCSR of this kind of ships becomes a great vital task
