Modeling and simulation of radar echo signal of aircraft targets with GRECO

In this paper, the complex RCS at several frequency in a certain bandwidth of the given target is simulated by GRECO method, which is based on the physical optics (PO) method and physical theory of diffraction (PTD) method, and the HRRP of the target is calculated with these wideband responses. By convoluting transmission pulse of the given radar and the HRRP of the target, the echo signal of the given target with the given radar can be obtained. The proposed technique is validated, and simulation results for an aircraft model is given.
