“…Active radar calibrators are used to calibrate the radar [ 16 , 17 , 18 ]. Thus, RCS has been extensively employed and investigated by various countries and experts [ 19 , 20 , 21 ]. Different full-wave analysis methodologies have been introduced during RCS investigation, such as the method of moment (MoM) [ 22 , 23 , 24 ] and finite difference time domain (FDTD) [ 25 , 26 , 27 , 28 ].…”

In order to analyze the scattering properties in multi-radiator problems, the active radar cross section (ARCS) concept is proposed under complex electromagnetic (EM) environments. The corresponding calculation methods and formulation are proposed by incorporating the monostatic radar cross section (RCS) concept with external disturbances. By introducing the phase characteristics into the ARCS concept, the coherent problems can be accurately solved. Through analyzing the external disturbance and the radar waves by employing the finite element method, the coherent and the incoherent characteristics of the external disturbance can be simulated in complex structures. Numerical examples and an experiment are carried out to further demonstrate the effectiveness of the proposed ARCS concept. The results demonstrate that the proposed ARCS concept obtains better universality compared with the existing incoherent multi-radiator formulation. Meanwhile, the ARCS can be identical with the solution which is obtained by the single radar wave. Compared with the existing incoherent methods for external disturbances calculations, the proposed ARCS concept is more rational. Through the experiment, the effectiveness of the calculation method and formulation is further demonstrated and validated.
