RCS calculation of a frequency band at arbitrary incidence angles and the components of aircraft using GRECO

GRECO method is regarded as one of the most effective method for high frequency approximation RCS calculation. It has many advantages such as little storage, fast speed and the calculation complexity not varying with the complexity and dimension of target. It is employed in this paper to calculate the RCS of a frequency band at arbitrary incidence angles quickly with a good precision by adjusting the view area within the screen automatically. In RCS reduction, we need to get the RCS contribution of components to the whole target. In this paper, the RCS contribution of the components to the whole target is also calculated which eliminates the shadow area from other components by hardware.
