 Survivability Analysis  RCS (Radar Cross-sectional area)  Engagement level modeling Results:The results obtained from the simulation shows that the RCS is most effective in simulations. Different results have been taken by changing the maneuver time and the data needed for it, and by changing the jamming power. Conclusion:In conclusion this research is completed and the effect of the RCS is observed. This model has many sub models that can be used in other designs. All these sub models are designed in engagement level.
